Wikipedia Robert Cailliau: Reference Audit | Network, Not Protocol

Of the 21 footnotes in Wikipedia’s article Robert Cailliau, 7 carry the sentence that cites them, and the claim that he “proposed the first (pre-www) hypertext system for CERN in 1987” rests on a page of How the Web Was Born that does not carry it, entered the article on July 31, 2018, and stands against his own speech of November 2, 1995, which lists his hypertext proposal under the year 1989.

Preamble: I audit the Wikipedia article Robert Cailliau footnote by footnote, opening the source that each footnote cites and reading it in full against the sentence that cites it. This page is the companion of Disagreement 101 in the standing index of the series, Disagreements of Published Claims | Network, Not Protocol, and the article lines cited on this page are the numbered lines of Exhibit A of Wikipedia Robert Cailliau: Disagreements | Network, Not Protocol.

0.0 This section records the article this page audits, the method of the audit, and the grades it assigns.

0.1 The article audited on this page is Robert Cailliau of the English Wikipedia at https://en.wikipedia.org/wiki/Robert_Cailliau, in revision 1373430061, the same revision that Disagreement 101 reproduces as its Exhibit A, and the article carries 21 numbered footnotes. This page read the list of footnotes, the links of each footnote and the sentences that cite each footnote through Wikipedia’s own public interface on November 14, 2026.

0.2 This page audited each footnote on November 14, 2026, by opening the source at the link the footnote gives, or at the archived copy that the footnote names where the original is gone, and by reading the source in full in a browser. The coverage of each source, fully read, partially read or not read, is stated in the unit that grades it.

0.3 Each footnote receives one of five grades. Supported means that the source carries the sentence in its own words. Partial means that the source carries part of the sentence and not the rest. Not supported means that the source was read and does not carry the sentence. Uncheckable means that the citation cannot be followed to a readable source. Unread means that the source was not read for this page.

0.4 The sources are quoted on this page in short fragments, and the rest of what each source says is stated in the words of this page. The sentences of the article are quoted in full from Exhibit A of Disagreement 101.

0.5 This page also read the revision history of the article through Wikipedia’s public interface on November 14, 2026, which lists 398 revisions, the first dated October 11, 2004, and section 2.0 and section 3.0 of this page rest on that history.

1.0 Each of the 21 footnotes of the article is graded on whether the source it cites carries the sentence that cites it.

1.1 Footnote 1, at line 55, cites How the Web Was Born, by James Gillies and Robert Cailliau, Oxford University Press, 28 September 2000, at page 197, for the claim at line 6 that Robert Cailliau “proposed the first (pre-www) hypertext system for CERN in 1987”. Disagreement 101 read page 197 in full on November 14, 2026, from an image that Mark Nichols supplied, and found at its section 1.0 that the page dates no proposal, names no document, makes no claim of a first, and uses the year 1987 only for his move to the computing division. Footnote 1 is graded Not supported.

1.2 Footnote 2, at line 56, cites the page “Past and Future Conferences of WWW” of the International World Wide Web Conferences Steering Committee, in the copy archived by the Internet Archive on June 25, 2010, for the claim at line 7 that Robert Cailliau organized the first International World Wide Web Conference at CERN in 1994. The archived page, fully read, says that the first conference “was held at CERN in 1994 and organized by Robert Cailliau.” Footnote 2 is graded Supported.

1.3 Footnote 3, at line 57, cites How the Web Was Born at “p. 0” for the claim at line 7 that Robert Cailliau helped transfer Web development from CERN to the global Web consortium in 1995. The citation gives page 0, and its link opens the book’s record at the Internet Archive with no page named, so the citation cannot be followed to a page. Footnote 3 is graded Uncheckable.

1.4 Footnote 4, at line 58, cites the article by Quentin Jardon of 5 March 2018 in the Belgian magazine 24h01, “Robert Cailliau, l’oublié du Web”, for the account of Robert Cailliau’s birth and education at line 10 through line 13 and for his military service at line 14. The link of the footnote now opens a guide to Belgian sports betting dated November 4, 2026, whose text, searched in full, does not contain the name Cailliau, and the copy archived by the Internet Archive on December 4, 2024 is a page offering the domain 24h01.be for sale. The copy archived on March 23, 2018, fully read, is the opening of the article only, and it sends the reader to the printed edition for the rest. The opening says that he was born in Tongeren in 1947, that he is an engineer in fluid mechanics from Ghent University, and that he took a specialization in computing in Michigan, and it gives no year for either degree and does not mention a move to Antwerp in 1958. On his military service it says that he served at the Royal Military Academy in Brussels, first as an auxiliary nurse and then as a computer programmer who invented and tested war video games, and it does not mention Fortran or the simulation of troop movements. Footnote 4 is graded Partial for line 13 and Partial for line 14.

1.5 Footnote 5, at line 59, cites “Knack dossiers : Het web van Tongeren” of the Belgian magazine Knack, recorded by the citation as retrieved on 21 December 2011 and archived on 6 February 2012, for the military service at line 14. The archived copy that the footnote names, fully read, is Knack’s own page saying that the page cannot be found, dated 6 February 2012, and the Internet Archive offers no other copy of the address under either spelling of it. The live address stopped at a human-verification check of the site, which this page did not pass around. Footnote 5 is graded Uncheckable.

1.6 Footnote 6, at line 60, cites “Why Do We Call It World Wide Web?” by Maureen Seaberg in Psychology Today, posted February 13, 2012, for the caption at line 15, “Historical World Wide Web logo designed by Robert Cailliau”. The article, fully read, quotes Robert Cailliau describing a logo made from three letters W in white, light green and darker green, and it names no designer of the logo. Footnote 6 is graded Not supported, and the credit for the logo is carried instead by the source of footnote 9, as unit 1.9 records.

1.7 Footnote 7, at line 61, cites the page “WWW people” of the World Wide Web Consortium, in its snapshot of 3 November 1992, for the account at line 16 and line 17 that Robert Cailliau joined CERN in December 1974 as a Fellow of the Proton Synchrotron division and in April 1987 left that division to lead the Office Computing Systems group of the Data Handling division. The page, fully read, says that he ran the Office Computing Systems group from 1987 to 1989, and it gives no month, names neither division, and gives no year for his arrival at CERN. The page’s entry for Robert Cailliau names no hypertext proposal of his. Footnote 7 is graded Partial.

1.8 Footnote 8, at line 62, cites CERN’s page “Ten Years Public Domain for the Original Web Software”, archived on November 16, 2010, for the claim at line 18 that Tim Berners-Lee proposed a hypertext system in 1989. The page, fully read, reproduces a CERN hand-out of 1997, which says that it all began in 1989 when Tim Berners-Lee proposed a distributed information system for CERN based on hypertext, and which says that Robert Cailliau joined Tim Berners-Lee in 1990. Footnote 8 is graded Supported.

1.9 Footnote 9, at line 63, cites “Frequently asked questions” by Tim Berners-Lee on the site of the World Wide Web Consortium, at its answer on Robert Cailliau’s role, and the article cites it three times. The page, fully read, says that Robert Cailliau wrote a proposal to CERN for staff to be allocated to the project “More than a year after my original proposal (March 1989)”, and the claim at line 20 that Cailliau and Berners-Lee co-authored a proposal for funding is graded Partial. The page names the Macintosh browser that Robert Cailliau wrote as Samba, and the claim at line 22 that he helped develop a browser called MacWWW is graded Partial. The page credits Robert Cailliau with organizing the first conference at CERN and gives no month for his call for it, and the claim at line 25 that he called for it in December 1993 is graded Partial. The same page says that Robert Cailliau made the WWW icon in many colors and chose green, which carries the credit for the logo that the caption at line 15 assigns to footnote 6. The same page also says of Robert Cailliau that he did not invent the World Wide Web and that it was not his idea.

1.10 Footnote 10, at line 64, cites How the Web Was Born at page 221 for the claim at line 21 that Robert Cailliau ran student projects to create browsers for several operating systems. Page 221 was not read for this page. Footnote 10 is graded Unread.

1.11 Footnote 11, at line 65, cites “Web Browser History” by Bill Stewart on the site Living Internet for the claim at line 22 that Robert Cailliau and Nicola Pellow developed the first web browser for the Classic Mac OS, called MacWWW. The page, fully read, says that Robert Cailliau started the first web browser for the Macintosh, that Nicola Pellow took up its development, and that the browser worked by the end of 1992, and it names the browser Samba. Footnote 11 is graded Partial.

1.12 Footnote 12, at line 66, cites the page “Macintosh Browser Status” of the World Wide Web Consortium, in its snapshot of 3 November 1992, for line 22. The page, fully read, names its authors as “RC, NP” and sets the first release for December 1992, and it does not use the name MacWWW or call the browser the first. Footnote 12 is graded Partial.

1.13 Footnote 13, at line 67, cites the page “Macintosh Browser” of the World Wide Web Consortium, in its snapshot of 3 November 1992, for line 22. The page, fully read, says that the Macintosh browser is written in Think-C, is signed “Tim BL”, and names neither Robert Cailliau nor Nicola Pellow. Footnote 13 is graded Not supported. Footnote 12 and footnote 13 carry the same citation text and link to two different pages, and none of the four sources that line 22 cites uses the name MacWWW. The browser archive of evolt.org, which the article WorldWideWeb cites at its footnote 11 and which was read for Wikipedia WorldWideWeb: Reference Audit | Network, Not Protocol, lists the Macintosh browser as “MacWWW (Samba)” and credits it to CERN, which joins the two names.

1.14 Footnote 14, at line 68, cites “History of the CERN Web Software Public Releases” by François Fluckiger and Tim Smith, CERN-IT-Note-2016-001 of January 21, 2016, recorded by the citation as retrieved on 31 July 2018, for the claim at line 24 that, as a result of Robert Cailliau’s work with CERN’s Legal Service, CERN’s director of Future Research Walter Hoogland signed the document that released the web technology into the public domain on 30 April 1993. The note, seven pages, fully read, says that the statement of 30 April 1993 was signed by Walter Hoogland as “Scientific Director” and followed internal lobbying by Tim Berners-Lee and Robert Cailliau, and it names CERN’s legal service only for the events of October 1994. The statement itself, held as L-028 and read on its page 2, is signed by W. Hoogland, Director of Research, and by H. Weber, Director of Administration, and neither the article nor the note names H. Weber. Footnote 14 is graded Partial.

1.15 Footnote 15, at line 69, cites “A Short History of the Web” by Robert Cailliau on the site NetValley, the text of his speech at the launch of the European branch of the World Wide Web Consortium in Paris on 2 November 1995, for the claim at line 25 that he called for the first conference in December 1993 and that it was held at CERN in May 1994. The speech, fully read, says under the year 1993 that he conceived the conference and began organizing it, and under the year 1994 that it was held at CERN, and it gives no month for either. Footnote 15 is graded Partial.

1.16 Footnote 16, at line 70, cites the same archived page of the International World Wide Web Conferences Steering Committee as footnote 2, for line 25. The page, fully read, dates the first conference to May 25 through May 27, 1994, at CERN, and it says nothing of a call for the conference in December 1993. Footnote 16 is graded Partial.

1.17 Footnote 17, at line 71, cites the working paper of Newropeans of 11 March 2009, archived on December 28, 2013, for the claim at line 32 that Robert Cailliau and Luca Cominassi drafted a proposal for Newropeans on the European information society. The paper, fully read, is signed by Robert Cailliau and Luca Cominassi and says that he is a member of Newropeans. Footnote 17 is graded Supported.

1.18 Footnote 18, at line 72, cites the list of the ACM Software System Award, archived on April 2, 2012, for line 36. The list, fully read, records the award of 1995 for the World-Wide Web to Tim Berners-Lee and Robert Cailliau. Footnote 18 is graded Supported.

1.19 Footnote 19, at line 73, cites the CERN Courier of July 2001, archived on April 2, 2015, for line 40. The notice, fully read, records that the city of Geneva selected Tim Berners-Lee and Robert Cailliau for the Genève Reconnaissante medal and that Robert Cailliau received it at a ceremony on 15 May. Footnote 19 is graded Supported.

1.20 Footnote 20, at line 74, cites the page of the Best of Swiss Web award for its Ehrenpreis of 2010, archived on March 29, 2010, for line 45. The page, fully read, says that the Ehrenpreis of 2010 goes to Robert Cailliau. Footnote 20 is graded Supported, and section 3.0 records the other claims on the same page.

1.21 Footnote 21, at line 75, cites the list of the 2012 inductees of the Internet Hall of Fame, archived on December 13, 2012, for line 46. The list, fully read, names Robert Cailliau among its Innovators. Footnote 21 is graded Supported.

2.0 The claim that Robert Cailliau proposed a hypertext system for CERN in 1987 entered the article on July 31, 2018, his own speech of November 2, 1995 lists his hypertext proposal under the year 1989, and his own recollection of November 1997, recorded by Charles Petrie of IEEE Internet Computing, places a hypertext project that he proposed for himself in 1987 and 1988, while no document of 1987 read for this page records a proposal of his.

2.1 The revision history of the article records that the claim at line 6 entered the article in revision 852770773 of July 31, 2018, made by the Wikipedia account Leenaars, with the edit summary “Incorporated major omissions documented in the seminal work” followed by the title How the Web Was Born, and with the citation of page 197 that is now footnote 1. Before that revision, the opening of the article described Robert Cailliau as the engineer who created the first web browser for the Mac.

2.2 The speech of Robert Cailliau of 2 November 1995, the source of footnote 15, lists under the year 1989 that Robert Cailliau “independently proposes a hypertext project for documentation handling inside the laboratory.” The only entry of the speech under the year 1987 records that CERN and the laboratories of the United States connected to the Internet. The same speech places the proposal of Tim Berners-Lee late in 1989, while his proposal is dated March 1989.

2.3 The page “WWW people” of 3 November 1992, the source of footnote 7, records Robert Cailliau as head of the Office Computing Systems group from 1987 to 1989 and names no hypertext proposal of his. The CERN hand-out of 1997, the source of footnote 8, says that Robert Cailliau joined Tim Berners-Lee in 1990. The answer of Tim Berners-Lee on Robert Cailliau’s role, the source of footnote 9, dates the proposal that Robert Cailliau wrote to more than a year after March 1989.

2.4 The article by Quentin Jardon of 5 March 2018, the source of footnote 4, reports a CERN brochure titled World-Wide Web, dated 9 March 1995 and signed by Robert Cailliau, whose first sentence, in the French of the article, says that it all began in 1989 when Tim Berners-Lee and Robert Cailliau proposed a distributed hypertext information system for CERN. The brochure itself was not read for this page, and this unit records only what the article reports of it.

2.5 Of the 17 sources that the article cites and that were read in full for this page, none dates a hypertext proposal of Robert Cailliau to 1987.

2.6 The conversation that Charles Petrie of IEEE Internet Computing recorded with Robert Cailliau in November 1997 is not cited by the article. It was read in full, in the copy archived on January 6, 2011, for Wikipedia WorldWideWeb: Reference Audit | Network, Not Protocol, and it is the one source read for this page that places a hypertext proposal of Robert Cailliau in 1987. In the conversation, Robert Cailliau says “we're talking about 1987 and '88” and says that he proposed a range of possible projects for himself, one of which was hypertext and another of which was the analysis of physics data with object-oriented systems and NeXTStep. He then says that he read the proposal of Tim Berners-Lee, essentially gave up and joined him immediately, and that their joint project proposal, called World Wide Web, dates to May 1990. The account is Robert Cailliau’s recollection of November 1997 and not a document of 1987. It describes projects that he proposed for his own work and not a system proposed for CERN, and it makes no claim of a first.

2.7 The introduction to the same conversation, written by Charles Petrie, gives the years of Robert Cailliau as head of Office Computing Systems at CERN as 1985 to 1989. The page “WWW people” of 3 November 1992 at footnote 7 gives 1987 to 1989, and the article at line 17 dates his move to that group to April 1987.

3.0 Four claims that the article carries without a supporting source appear in a Wikipedia revision of March 26, 2010, three days before the Best of Swiss Web page of 2010, which carries the same four claims, was archived.

3.1 The article carries four claims that no source read for this page supports: the clause at line 24 that the public domain release came as a result of Robert Cailliau’s work with CERN’s Legal Service, the claim at line 26 that the first conference brought together 380 web pioneers, the claim at line 28 that he was a founding member of the conference committee from 1994 until 2002, and the claim at line 29 that he started the project Web for Schools with the European Commission, which the article now dates to 1995. line 26, line 28 and line 29 carry no footnote.

3.2 Revision 352117322 of the article, dated March 26, 2010 in Wikipedia’s revision history, already carried all four claims, with the Legal Service, the 380 web pioneers, membership of the committee from 1994 until 2002, and the start of Web for Schools in 1994.

3.3 The page of the Best of Swiss Web award for its Ehrenpreis of 2010, the source of footnote 20, archived on March 29, 2010 and fully read, carries the same four claims in German, with the start of Web for Schools in 1994, and the same page gives the years of his membership of the committee both as 1994 to 2004 and as 1994 to 2002. The same page also says that Robert Cailliau has worked at CERN since December 1964 and took his degree at the University of Michigan in 1971, where the article says December 1974 and 1972.

3.4 On the dates of the two records, the Wikipedia revision of March 26, 2010 is the earlier of the two, and this page does not establish whether the Best of Swiss Web page was written from the article or the article from another source.

3.5 On the number of persons at the first conference, the speech of Robert Cailliau of 2 November 1995 says that it attracted over 600 and admitted 400, and the page of the World Wide Web Consortium examined at W3C A Little History of the World Wide Web: Disagreements | Network, Not Protocol says that 800 applied and 400 were allowed in. Neither gives the figure 380.

4.0 Of the 21 footnotes, 7 carry the sentence that cites them, 8 carry it in part, 3 do not carry it, 2 cannot be checked, and 1 was not read.

4.1 Footnotes 2, 8, 17, 18, 19, 20 and 21 are graded Supported, and footnotes 18 through 21 support entries in the list of awards of the article.

4.2 Footnotes 4, 7, 9, 11, 12, 14, 15 and 16 are graded Partial, and each carries a name or a year that the article states while differing from or leaving out the rest of the sentence that cites it.

4.3 Footnotes 1, 6 and 13 are graded Not supported, and footnote 1 is the only footnote of the claim of 1987 at line 6.

4.4 Footnotes 3 and 5 are graded Uncheckable, and footnote 10 is graded Unread until page 221 of How the Web Was Born is read.

5.0 The claims on this page are open to documented challenge on the standing terms of marknichols.com, and the terms are stated here in full.

5.1 The claims on this page are open to challenge on the same terms as every claim on marknichols.com. A challenger who holds that a claim on this page is wrong, or that the Internet is something other than the publicly joinable network of networks of the registry lineage defined at The Governing Definitions and Controlling Facts of Telecommunications Internetworking, states the competing claim or definition in one sentence, names the document that carries it and the document’s date, and sends both to mark@marknichols.com. A challenge submitted with its document is answered on this page, and a competing definition submitted with its document is added to this page as an exhibit with attribution to the person who submitted it; a challenge submitted without a document is an opinion and is heard as one.

5.2 The distinction the site’s definition rests on, that protocols enable interoperability and are not the Internet, is stated in the IETF’s own words, RFC 2026 and STD 1, in the Internet-Draft draft-mnichols-protocols-not-the-internet-01, posted by Mark Nichols to the IETF Datatracker on September 25, 2026 at https://datatracker.ietf.org/doc/draft-mnichols-protocols-not-the-internet/ and stated on this site at Protocols Are Not the Internet: The IETF Internet-Draft by Mark Nichols, so a challenger may also address the definition in the venue that publishes the protocol standards themselves. Any person who holds expertise in telecommunications and a competing claim or definition is invited to bring both, in writing, with the document.

6.0 The Definitions Addendum reproduces the Governing Definitions D1 through D13 of marknichols.com word for word, and every finding on this page is made under them.

6.1 Every finding on this page is made under the Governing Definitions of marknichols.com, D1 through D13, which are reproduced in this addendum word for word from The Governing Definitions and Controlling Facts of Telecommunications Internetworking. A reader of this page either accepts these definitions or disputes them. A reader who disputes a definition states the competing definition in one sentence and names the dated document that carries it before opining on any finding of this page. A reader who opines on the findings without disputing a definition has read the findings under these definitions by default.

6.2 The definitions below are copied word for word from the section “These definitions are employed throughout marknichols.com” of The Governing Definitions and Controlling Facts of Telecommunications Internetworking, as that page read on November 13, 2026, and that page controls wherever a copy differs from it.

D1. The Internet (capital I). The publicly joinable network of networks of the registry lineage: the fabric whose addresses and autonomous system numbers were issued by the InterNIC and are maintained today by ARIN. A person joins it by purchasing access from any of competing commercial providers, for any lawful purpose, and a network joins it by obtaining addresses and an autonomous system number from the numbering registry and then interconnecting by agreement with any willing network, the way Digital Island joined under autonomous system AS6553, issued August 29, 1996 by the InterNIC, with the registration maintained today in ARIN’s registry. No owner grants admission, no written policy screens members or their purposes, and no government sponsorship is required, and that single property, open admission, is what separates the Internet from every gated network that existed before it. The capital-I Internet was born in 1991, when independently operated commercial networks of this lineage, PSINet, AlterNet under UUNET, and CERFnet, interconnected by their own agreement as the Commercial Internet eXchange (CIX), settlement-free and free of any purpose-screening policy, and it was born small: the gated research world stood beside it until April 30, 1995, upon the decommission of NSFNET folded into internetMCI, per orders of Congress. Neither the ARPANET intranet, which admitted members only by agency authorization, nor the NSFNET intranet, which admitted members only under a written Acceptable Use Policy restricted to research and education, met this definition on any day of either existence, so the capital I names an Internet network that is public, or it names nothing. Paragraphs D1.1 through D1.7 state why the ARPANET and the NSFNET are not in the lineage of the Internet, each on its document.

D1.1 A network stands in the lineage of the Internet only if it carried the trait that defines the Internet, and D1 names that trait as one property, open admission; a network that never carried open admission had no such trait to pass on, and the ARPANET and the NSFNET never carried it, so neither the ARPANET nor the NSFNET is the grandfather, the ancestor, the parent, or the precursor of the Internet, and neither the ARPANET nor the NSFNET became the Internet.

D1.2 The ARPANET admitted members by its owner’s authorization from its procurement to its end: Request for Quotations No. DAHC15 69 Q 0002, issued July 29, 1968 for the Advanced Research Projects Agency of the United States Department of Defense, states the network’s purpose as “making these advanced research computer systems available to users outside their own design circle,” a purpose among the owner’s research contractors, as F37 of this page records; admission ran through agency authorization, as D4 of this page records; and the ARPANET ran from 1969 to 1990, as F38 of this page records, so the ARPANET was an intranet under D2 on every day of its existence and never carried open admission.

D1.3 The NSFNET admitted members only under a written Acceptable Use Policy restricted to research and education, as D7 of this page records, and its backbone was terminated on April 30, 1995, when its regional networks passed principally to internetMCI and SprintLink, which, in the words of Merit Network, the operator of record, absorbed the NSFNET regionals as their customers, so the NSFNET’s member networks joined the Internet as customers on terms the NSFNET never offered, and the NSFNET itself ended and did not become the Internet.

D1.4 The trait that defines the Internet has a documented origin outside the gated networks: the release of March 25, 1991 by General Atomics, Performance Systems International, Inc., and UUNET Technologies, Inc., seated at F52 of this page, states that the three networks “are not subject to government mandated “acceptable use” restrictions on their traffic,” states that the agreement can be expanded “to include any commercial service which has no restrictions on traffic use,” and states that the exchange allows firms to communicate “without traversing the government restricted backbones, such as the NSFNET (National Science Foundation Network),” so the Internet was built by agreement among commercial networks to carry traffic around the gated backbone, and the Internet did not grow out of the gated backbone.

D1.5 The ARPANET, the NSFNET, and the Internet each performed internetworking under D3, and a shared function is not a shared lineage: RFC 2026, The Internet Standards Process, Revision 3, by Scott O. Bradner of Harvard University, published October 1996, states at its section 1.1 that “There are also many isolated interconnected networks, which are not connected to the global Internet but use the Internet Standards,” so a network that uses the same protocols as the Internet is a user of the same tools and is not thereby the Internet or its ancestor. A redwood and a palm are both called trees, and a redwood did not grow from a palm, and a palm cannot become a redwood; the gated internets of the ARPANET and the NSFNET and the capital-I Internet are both called internets, and the shared word names a shared function and not a shared tree. The shared word was applied to the gated networks in error, and this record documents the error by document and date: the Stanford University bronze dedicated July 28, 2005 casts the headline “BIRTH OF THE INTERNET” above an inscription that records protocol work, as Stanford University Is Petitioned to Retract the Headline of Its BIRTH OF THE INTERNET Plaque records; RFC 1208, A Glossary of Networking Terms, by Ole J. Jacobsen and Daniel C. Lynch of Interop, Inc., published March 1991 as a document that in its own words “does not specify an Internet standard,” calls the ARPANET the “grandfather” of today’s Internet with no document for the descent it asserts; and IEEE Milestone 94 of October 29, 2009 is titled “Birthplace of the Internet, 1969,” as F46.1 of this page records.

D1.6 The registry lineage named in D1 is a continuity of numbering administration, the assignment of network addresses and autonomous system numbers by the Network Information Center at SRI, then by the InterNIC, and today by ARIN, and the registry lineage is not a lineage of networks: the Network Information Center at SRI kept the Official Host Table of the ARPANET’s era, as D4 of this page records, and a number assigned by a registry admits no one to any network, so the continuity of the numbering places no gated network in the lineage of the Internet.

D1.7 On every page of marknichols.com, the ARPANET and the NSFNET are named earlier gated networks, networks that also performed internetworking, or intranets under D2, and no page of marknichols.com calls either network the grandfather, the ancestor, the parent, the precursor, or the forerunner of the Internet, places either network in the lineage of the Internet, or states that either network became, evolved into, or grew into the Internet, under the ruling of Mark Nichols of November 7, 2026 that the ARPANET and the NSFNET belong to the history of internetworking and not to the lineage of the Internet, and that the Internet is a separate species.

D1.8 The plain statements of D1.1 through D1.7 are these. The ARPANET is not the Internet. The NSFNET is not the Internet. The ARPANET did not become the Internet. The NSFNET did not become the Internet. The ARPANET is not the grandfather, the ancestor, the parent, or the precursor of the Internet. The NSFNET is not the grandfather, the ancestor, the parent, or the precursor of the Internet. The ARPANET was an intranet, because the Advanced Research Projects Agency of the United States Department of Defense owned the ARPANET and admitted the ARPANET’s members by permission. The NSFNET was an intranet, because the NSFNET backbone admitted members only under a written Acceptable Use Policy restricted to research and education. The Internet admits anyone, and open admission is the one property that defines the Internet. Open admission came to the Internet from the commercial networks PSINet, AlterNet, and CERFnet at the Commercial Internet eXchange announced on March 25, 1991, and open admission did not come from the ARPANET or from the NSFNET. The ARPANET ended in 1990. The NSFNET backbone ended on April 30, 1995. The ARPANET, the NSFNET, and the Internet share the function of internetworking and share the word internet, and a shared function and a shared word are not a shared lineage. The Internet was born in 1991, and the Internet was not born from the ARPANET or from the NSFNET.

D2. intranet. A network, at any scale, in any geography, and under any protocol, whose members join by an owner’s permission. The word carries its own definition: intra means within, and an intranet is a network within a bounded and credentialed community, whether that community is one company’s offices or one government’s contractors spread across two continents. Scale does not convert an intranet into the Internet, geography does not, and protocol does not, because a gated network that adopts the optional protocols TCP/IP has changed its plumbing and not its admission policy; only open admission makes the Internet, and a research intranet is not the Internet. NSFNET and ARPANET are historical examples of intranets under this definition. Neither was the Internet, and neither became the Internet merely by being technically interconnected with other networks.

D3. internetworking. The technique of interconnecting distinct networks through gateways so that traffic originating on one can reach hosts on another. Internetworking among gated intranets was operating in production by 1975, when the gateway at University College London, developed and operated by Peter Kirstein’s group, of which Peter Higginson was a principal member, joined the ARPANET to the United Kingdom’s EPSS, an operation documented in the September 1975 paper of Peter L. Higginson and Andrew J. Hinchley, which recorded the working gateway while filing the Cerf and Kahn protocol as a future option rather than the operating method. Internetworking among gated intranets makes a lowercase internet, in the exact lowercase vocabulary of RFC 1983, and it never makes the capital-I Internet, because interconnecting two gated networks produces a larger gated system, not a public one. The credit for internetworking belongs to the engineers who built and operated the gateways; that credit does not extend to the birth of the Internet, which did not yet exist.

D4. ARPANET, also rendered DARPANET. The ARPA Network: one organization’s intranet, built, funded, owned, and access-controlled by the Advanced Research Projects Agency of the United States Department of Defense, later renamed DARPA, from its commissioning in 1969 until its decommissioning in 1990. Its very name is a possessive, the agency’s initials welded onto the agency’s property, and the network’s renamings followed the owner’s renamings, as only an owned network’s can. Admission was by the owner’s authorization for the owner’s purposes, the Official Host Table of the Network Information Center at SRI, the register of the era’s hosts that preceded the optional protocol DNS, listed 235 hosts in May 1982 and 562 hosts in August 1983, the two counts in RFC 1296 of January 1992 that bracket the 1983 protocol cutover, and no member of the public could join it, buy from it, or sell across it on any day of its twenty-one years. The owner stated the network’s purpose in its own procurement instrument before the network existed: Request for Quotations No. DAHC15 69 Q 0002, issued July 29, 1968 by the Defense Supply Service-Washington of the Department of the Army for the Advanced Research Projects Agency under ARPA Order No. 1260, and signed by Thomas J. Scheblik, Deputy Director for Procurement, solicited the Interface Message Processors for the ARPA computer network, and its Statement of Work, Specifications of Interface Message Processors for the ARPA Computer Network, states that the Agency was forming the network “with the cooperation of its research contractors,” that the network’s potential lay in “making these advanced research computer systems available to users outside their own design circle,” and that the network itself was “a subject of study and experimentation,” while the Statement of Work’s nineteen pages and seven appendices contain no reference to war, to survivability, to attack, to command and control, or to any military mission. The design mission of the ARPANET was therefore resource sharing among the owner’s research contractors, stated by the owner in 1968, and the later recollections agree with the instrument: Charles Herzfeld, Director of ARPA from 1965 to 1967, stated that the ARPANET was not started to create a command and control system that would survive a nuclear attack; Vint Cerf recorded on the Internet Society’s internet-history list on September 1, 2009 that Larry Roberts confirmed the purpose of the ARPANET was resource sharing and that the nuclear resilience story came from Paul Baran’s earlier work; and the Internet Society’s own history, A Brief History of the Internet, calls that story a false rumor that arose from the unrelated RAND study. The wartime mission, command traffic surviving damaged links and destroyed nodes, belonged to the owner’s later internetting project, which Vint Cerf managed at DARPA and demonstrated by putting packet radios in Strategic Air Command aircraft, and the optional protocol TCP, specified in 1974 with military computer communication requirements as the stated primary focus of RFC 793 of September 1981, was designed for that mission and installed on this intranet by the owner’s directive in 1983. The ARPANET is not the Internet, and DARPANET is not the Internet: one organization’s intranet is not the publicly joinable network of networks. The ARPANET intranet was procured under Request for Quotations No. DAHC15 69 Q 0002 of July 29, 1968, ran from 1969, and carried its traffic for fourteen years, under the Network Control Program, an optional protocol first specified in RFC 33 of February 1970, before TCP was added to it on January 1, 1983; a protocol added to a working network fourteen years after the network was procured is an add-on to that network, not its birth.

D5. Flag day, January 1, 1983. A scheduled protocol cutover, from NCP to TCP/IP, planned within the ARPANET community for years and executed on the owner’s own plant: an intranet’s internal maintenance event, touching no member of the public because no member of the public was on the network before the cutover or after it. The protocol installed that day was commissioned by the same owner to weld its own three networks together, the terrestrial ARPANET, its mobile packet radio network, and its satellite network, crossing dissimilar media under a single owner without ever crossing an owner, so that traffic could survive battlefield destruction. The Internet’s own standards registry graded TCP “Recommended” and never “Required,” in RFC 1200 of April 1991 and RFC 2200 of June 1997, grades that bind only systems electing to implement the standard suite, and a protocol cutover on a gated intranet is not the birth of anything. The network the protocol was cut over onto had been procured on July 29, 1968 and running since 1969, fourteen years before that day, so the cutover added a protocol to an existing intranet and created no network.

D6. The Internet protocols, the optional protocols TCP and IP. Protocols are utilities whose messages the networks carry; they are not the networks, and they are not the Internet. Under these Governing Definitions, TCP and IP are optional protocols, and paragraphs D6.1 through D6.13 state the documents on which that definition rests and the judgment of Mark Nichols that completes it.

D6.1 The Internet’s own standards registry, issued first by the Internet Activities Board and later by the Internet Architecture Board, under the title IAB Official Protocol Standards and from RFC 1500 of August 1993 under the title Internet Official Protocol Standards, assigned a status to each listed protocol in twenty-two editions, from RFC 1083 of December 1988 through RFC 2400 of September 1998.

D6.2 Every one of those twenty-two editions lists TCP, the Transmission Control Protocol of RFC 793, at the status “Recommended”, printed “Rec” from RFC 1280 of March 1992 onward, and lists IP, the Internet Protocol of RFC 791, at the status “Required”, printed “Req” from RFC 1280 onward, and not one of the twenty-two editions lists TCP at the status “Required” in any of its tables.

D6.3 RFC 1200 of April 1991, issued by the Internet Activities Board with Jon Postel as editor, and RFC 2200 of June 1997, issued by the Internet Architecture Board with Jon Postel as editor, each define the status “Required” at section 4.2.1 in the words “A system must implement the required protocols”, define the status “Recommended” at section 4.2.2 in the words “A system should implement the recommended protocols”, and define the status “Elective” at section 4.2.3 in the words “A system may or may not implement an elective protocol”, so that by the registry’s own definitions TCP is a protocol that a system should implement and is not a protocol that a system must implement.

D6.4 RFC 1200 of April 1991 and RFC 2200 of June 1997 each open by stating that the edition “describes the state of standardization of protocols used in the Internet” as determined by its board, and each states that “Few protocols are required to be implemented in all systems” because of the variety of possible systems, gateways, terminal servers, workstations and multi-user hosts among them.

D6.5 RFC 1122, Requirements for Internet Hosts -- Communication Layers, edited by Robert Braden for the Internet Engineering Task Force in October 1989 and listed at the status “Required” in RFC 2200 of June 1997, states at its section 1.1.3 that “To communicate using the Internet system, a host must implement the layered set of protocols comprising the Internet protocol suite” and, in the next sentence, that “A host typically must implement at least one protocol from each layer”, so RFC 1122 binds a host that has chosen to communicate using the Internet system, and RFC 1122 requires of that host at least one transport protocol, not TCP.

D6.6 RFC 1122 of October 1989 states at its section 1.1.3 that “There are two primary transport layer protocols at present”, naming TCP and UDP, and that “the set of official Internet transport protocols may be expanded in the future”, states at its section 4.2.1 that “TCP is used by those applications needing reliable, connection-oriented transport service”, and states at its section 4.1.1 that “UDP is used by applications that do not require the level of service of TCP”, so RFC 1122 itself assigns TCP by the needs of the application.

D6.7 RFC 1200 of April 1991 and RFC 2200 of June 1997 each list, at section 6.3, Network-Specific Standard Protocols, the transmission of IP over each type of physical network, ARPANET, X.25, Ethernet, IEEE 802, FDDI and serial lines among them, at the status “Elective”, and each states that “it is elective to support any particular type of physical network” on which IP is transmitted.

D6.8 RFC 2500 of June 1999 prints no status for TCP or for IP, RFC 5000 of May 2008, the last edition of the registry, prints no status for TCP or for IP, and RFC 7100 of December 2013, written by Pete Resnick of Qualcomm Technologies, Inc., obsoletes RFC 5000 and requests that RFC 5000, and therefore STD 1, be moved to Historic status, so the last status that the Internet’s own standards registry ever assigned to TCP is “Recommended”, in RFC 2400 of September 1998.

D6.9 The IP that the registry listed at the status “Required” is version 4 of the Internet Protocol, RFC 791, and the Internet Engineering Task Force standardized a second and separate Internet Protocol, version 6, in RFC 8200 of July 2017, STD 86, by S. Deering and R. Hinden. RFC 6540 of April 2012, BCP 177, titled IPv6 Support Required for All IP-Capable Nodes and written by W. George of Time Warner Cable, C. Donley of CableLabs, C. Liljenstolpe of Big Switch Networks and L. Howard of Time Warner Cable, advises that “IPv6 support is no longer considered optional”, cautions that the term “IP” has become “a generic that can mean IPv4 + IPv6, IPv6-only, or IPv4-only, depending on context and application”, and states that new and updated IP networking implementations “must not require IPv4 for proper and complete function”, so the Internet Engineering Task Force itself used the word optional for an Internet Protocol until April 2012, and the IP version that the registry listed at the status “Required” is, under the Best Current Practice of April 2012, a version that no new or updated implementation may require.

D6.10 The suite’s own members prove reliability is a per-application choice, because the optional protocols UDP of RFC 768, RTP of RFC 1889 of January 1996, which RFC 3550 of July 2003 obsoletes, and QUIC of RFC 9000 all decline TCP’s services while each remains a protocol of the Internet standards track.

D6.11 TCP is an evolutionary option, not a permanent fixture: it replaced NCP on the owner’s intranet in the 1983 cutover, UDP stood beside it from 1980 for applications that declined its services, RTP went around it in 1996 for media that could not wait for retransmission, and QUIC, published in May 2021, is displacing it now by moving reliability into a new protocol carried inside UDP datagrams; the protocols rotate while the Internet persists, and a layer whose occupants rotate is by definition not the thing itself.

D6.12 It is the stated judgment of Mark Nichols that both are optional utilities: TCP optional on the registry’s own grade, and IP optional as a specific protocol, because the registry’s “Required” grade is conditional conformance language that binds only systems electing to implement the standard suite, the election being made before the grade applies, as the words “To communicate using the Internet system” of RFC 1122 and the word optional that RFC 6540 applies to IPv6 both record, and because what internetworking requires is the addressing function, the label that says where a packet should go, while IP is one implementation of that function and not the function itself.

D6.13 Hence the rebrand coinages stated at marknichols.com/internet-protocols/: TCP is better named ESFRP, the Endpoint Segment Failure Retry Protocol, and IP is better named ALP, the Address Label Protocol. The postmen are not the post office, and the protocols are not the Internet.

D7. NSFNET. The National Science Foundation’s backbone, 1986 to 1995: a federation of research intranets joined into a lowercase internet under a written Acceptable Use Policy that restricted carriage to research and education and barred commercial traffic. The dismantling is dated by the operator of record, Merit Network: the replacement architecture was awarded early in 1994, the very high speed Backbone Network Service to MCI and the Network Access Points to Sprint, MFS Datanet, and Bellcore representing Ameritech and PacBell; member networks began moving off in November 1994; the backbone was terminated on April 30, 1995; and the regional networks passed principally to the commercial carriers internetMCI and SprintLink, which, in Merit’s own words, absorbed the NSFNET regionals as their customers. The NSFNET is not the Internet: a backbone admission-screened under a written Acceptable Use Policy restricted to research and education is a gated network, and a gated network is not the publicly joinable network of networks.

D8. The World Wide Web. An application design made by many persons inside and outside CERN, announced publicly on August 6, 1991, three programs of CERN's World Wide Web software, the line-mode client, the basic server and the library of common code, released into the public domain by CERN on April 30, 1993, with NCSA Mosaic released in 1993 putting a graphical browser in front of it. A free application is not an open network: until April 30, 1995, the Web’s principal carriage was the gated research intranets beneath it, research-only carriage under the written policy, and the calendar states the dependency exactly, because CERN's three programs of Web software went public on April 30, 1993, and the gated research fabric beneath most of its hosts was absorbed into the public Internet two years later to the day, on April 30, 1995. The name World Wide Web is a label for a large body of technology in the public domain, made by many persons and bodies inside and outside CERN, as F32.4 of this page states. The World Wide Web is not the Internet: the Web is an application using the Internet platform, and the application is not the platform.

D9. The birth of the Internet, and the absorption. The capital-I Internet was born in 1991, when PSINet, AlterNet under UUNET, and CERFnet, independently operated commercial networks of the registry lineage, established the Commercial Internet eXchange, a settlement-free router interconnection with open admission and no purpose-screening policy, as recorded in the Federal Communications Commission working paper The Digital Handshake by Michael Kende and as announced by the three networks’ operators themselves, General Atomics, Performance Systems International, Inc., and UUNET Technologies, Inc., in their release of March 25, 1991, which states that “The CIX agreement provides for all customers of AlterNet, CERFnet and PSINet to exchange Internet traffic directly, regardless of which network the customer obtains service from, and at no additional cost” and that the three “are not subject to government mandated “acceptable use” restrictions on their traffic,” the release being preserved as message 441 of the com-priv archive at the Massachusetts Institute of Technology and seated at F52 of this page; the agreement’s own text and its execution date are still sought, and the ruling stands on the dated announcement, the year, the parties, and the terms until a dated earlier instrument of the same lineage is produced. April 30, 1995 is not the Internet’s birthday; it is the absorption: the day the last written admission policy over the general-purpose research backbone died with the NSFNET, the regional networks passed principally to internetMCI and SprintLink, and the populations that had lived behind the gate joined the Internet that had existed without them since 1991. Being born is not the same as being built, and the Modern Internet, publicly accessible, eCommerce native, media streaming native, and QoS native, was built from 1996 to 1997 on executed documents: the Telecommunications Act signed February 8, 1996, autonomous system AS6553 issued August 29, 1996 by the InterNIC, the $300,000 Cisco Systems agreement of November 1996 to host cisco.com on Digital Island’s Tier-0 network, and production service in the first quarter of 1997, with Cisco Systems, Stanford University, and Visa International as the first customers in sequence.

D10. The Modern Internet. The Internet changed from the legacy Internet to the Modern Internet on the day its internetworking changed from best effort to deterministic, and that day is November 1, 1996, the Effective Date of the Cisco Systems Remote Data Services Agreement, signed for Digital Island, Inc. by Mark Nichols, Director, Global Networks, on November 7, 1996 and for Cisco Systems, Inc. by Hervé Goguely, Director, Global Service Management, on November 8, 1996, under which Cisco Systems became the first customer to buy a contractually guaranteed global service, a network segment exclusively its own with secure transaction services and sub-300 milliseconds round trip, on the architecture Mark Nichols hand-drew in June 1996, redrew as DIGITAL ISLAND DRAFT.1 in July 1996 and DRAFT.2 in October 1996, and registered as AS6553, issued to Digital Island, Inc. on August 29, 1996. An evolution, not a synonym. The capital-I Internet born in 1991 and made general-purpose by the absorption of April 30, 1995 was public but bare: a network anyone could join, and nothing commerce-grade could yet depend on, because open admission supplies members and does not supply performance. The Modern Internet is what that public network evolved into when global commerce was engineered onto it: the enabling of the globalization of eCommerce, of streaming media, and of Quality of Service under signed and enforceable terms, built on Digital Island’s Tier-0 network under autonomous system AS6553 with contractually enforced sub-300-millisecond round-trip performance across major markets, carrying the Merchant Transport product category coined in September 1996, on the architecture designed by Mark Nichols as co-founder and chief architect, the record standing at marknichols.com/architect-of-the-modern-internet/, marknichols.com/merchant-transport/, and marknichols.com/tier-0/. The evolution is dated by the executed record and by the customers who ran on AS6553 in sequence: Cisco Systems in November 1996, Stanford University in 1997, Visa International in the second quarter of 1997, E*TRADE under its global data distribution agreement with Digital Island dated August 1, 1997, as Digital Island’s S-1 records it, Charles Schwab in 1998, and MasterCard in March 1999; Telefónica Data formed a global IP alliance with Digital Island on April 26, 1999, Sun Microsystems and Inktomi invested in Digital Island in December 1999, Microsoft, Intel, and Compaq invested in Digital Island in June 2000, and CERNET, the China Education and Research Network, peered with Digital Island under the contract signed in Beijing on February 25, 1998 and was never a customer. The Modern Internet is therefore dated 1996 to 1997 in executed documents, and the word modern means publicly accessible, commerce-grade, streaming-capable, and QoS-governed, none of which the newborn network possessed.

D11. Usage. On every page of this site, Internet with a capital I means the publicly joinable network of the registry lineage born in 1991 and nothing else; internet in lowercase means any interconnection of networks, including gated ones; gated systems are named what they were, research intranets, whatever their date; and any page, headline, plaque, or biography that assigns the birth of the Internet to 1969, 1974, or 1983 is measured against these definitions and fails, because on each of those dates every network in the claim admitted its members by permission, and any account that assigns the birth to April 30, 1995 is measured against these definitions and fails as well, because on that date the Internet already existed and what died was the gate beside it. And on every page of this site, “Required” as a registry grade appears only in quotation marks with its condition stated in the same sentence, that it binds only systems electing to implement the standard suite, except within D6 of this page, where D6.12 states that condition once for every quotation of the registry in D6.1 through D6.11; this site’s own prose never calls any Internet protocol required, because at the level of Internet membership there are no required protocols, only elected ones, and an unconditional “required” applied to an Internet protocol is the registry’s conditional conformance label promoted into a membership law that no document states.

D12. Contemporary primary-source documents control over retrospective accounts, institutional narratives, biographies, media summaries, machine-generated responses, and personal recollections.

D13. Any finding in this record may be amended upon production of contemporaneous documentary evidence demonstrating a materially earlier, later, or contrary fact.
