Wikipedia WorldWideWeb: Reference Audit | Network, Not Protocol
Of the 34 citations in Wikipedia’s article WorldWideWeb, 21 carry the sentence that cites them, and none of the citations behind its claim that the source code of WorldWideWeb was released into the public domain on 30 April 1993 carries that claim, because the statement of that date puts three other programs of CERN into the public domain and the source given for Tim Berners-Lee’s choice of the public domain concerns the library of common code.
Preamble: I audit the Wikipedia article WorldWideWeb 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 99 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 WorldWideWeb: Disagreements | Network, Not Protocol. The method and the five grades are the same as on Wikipedia Robert Cailliau: Reference Audit | Network, Not Protocol.
Opinion Rules: You are visiting my record, and I am the subject matter expert on it. If you are a subject matter expert too, I want to hear from you: bring your document and I will answer it on the record. If you are not, you are welcome here to read and to learn. The documented-challenge terms of marknichols.com and the condition on opinion are stated at F40 of The Governing Definitions and Controlling Facts of Telecommunications Internetworking, and they govern this page.
Conditional on the Governing Definitions: Every finding on this page is conditional on the Governing Definitions D1 through D13 of marknichols.com, which are reproduced in full in the Definitions Addendum at the bottom of this page.
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 WorldWideWeb of the English Wikipedia at https://en.wikipedia.org/wiki/WorldWideWeb. Wikipedia’s revision history records revision 1375089839 of September 15, 2026 as the latest revision of the article on November 14, 2026, the day on which Disagreement 99 read the text that Mark Nichols supplied. The article carries 14 numbered footnotes, which it cites 34 times. This page read the list of footnotes, the links of each footnote and the sentences that cite each footnote in revision 1375089839 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, at the archived copy that the footnote names where the original is gone, and, where the footnote names no copy, at an archived copy that this page identifies in the unit that grades it. Each source was read in full, and the coverage of each source is stated in the unit that grades it.
0.3 Each citation 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 from Exhibit A of Disagreement 99.
1.0 Each of the 14 footnotes of the article is graded at each sentence that cites it.
1.1 Footnote 1, at line 54, cites “The WorldWideWeb browser” by Tim Berners-Lee on the site of the World Wide Web Consortium, and the article cites it nine times. The page, fully read, says that the first web browser was called WorldWideWeb, was written in 1990, was later renamed Nexus, was written in Objective-C on a NeXT computer, became hypertext by subclassing the Text object, did not at first show inline images, and could browse but not edit remote documents because HTTP PUT was not implemented. The citations at line 10, line 11, line 18, line 37, line 41, line 42 and line 45 are graded Supported.
1.2 At line 7, the infobox gives the release of WorldWideWeb as 25 December 1990. The page of footnote 1 says that the first edition was “whimsically dated 901225” and was prepared before Christmas, which makes the date a label on the first edition and not a release. The citation is graded Partial. At line 46, the article describes a navigation panel with Next and Previous buttons, and the page of footnote 1 describes a Navigate menu with back, next and previous, and the citation is graded Partial. The navigation panel with five buttons is described instead by the source of footnote 9.
1.3 Footnote 2, at line 55, cites “The document that officially put the World Wide Web into the public domain on 30 April 1993”, the record CERN-IT-9304003 of the CERN Document Server, for the infobox licence at line 14, “Public-domain software”, and for the claim at line 21 that the source code of WorldWideWeb was released into the public domain on 30 April 1993. The record, fully read with both of its images, is the statement of CERN of 30 April 1993 that this site holds as L-028. Its declaration puts three programs into the public domain, the W3 basic (“line-mode”) client, the W3 basic server and the W3 library of common code, and it does not name WorldWideWeb. Both citations are graded Not supported.
1.4 Footnote 3, at line 56, cites “Robert Cailliau on the WWW Proposal: ‘How It Really Happened.’”, the conversation that Charles Petrie of IEEE Internet Computing recorded with Robert Cailliau in November 1997, in the copy archived on January 6, 2011, and the article cites it five times. The interview, fully read, says that the NeXTStep program was a browser and editor, that it could display PostScript, that it was all WYSIWYG, and that a user who needed more than one page of bookmarks made new local HTML pages, and the citations at line 18, line 38, line 42 and line 48 are graded Supported. At line 30, the article says that nobody on the team knew the X Window System, and Robert Cailliau says that neither he nor Tim Berners-Lee had X knowledge, and the citation is graded Partial.
1.5 Footnote 4, at line 57, cites “Frequently asked questions” by Tim Berners-Lee at its answer on the first browsers, and the article cites it six times. The page, fully read, says that he wrote the first GUI browser in 1990 on the NeXT computer, that it used style sheets, and that it displayed sounds, animations and movies, and the citations at line 23 and at the style sheets and the movies and sounds of line 38 are graded Supported. It does not name PostScript, and that citation at line 38 is graded Partial. It says that the original version showed some icons in separate windows and does not mention the Text class or Image objects, and the citation at line 39 is graded Partial. It gives no date of release into the public domain and says only that the code has always been publicly available, and the citation at line 21 is graded Not supported.
1.6 Footnote 5, at line 58, cites “A Brief History of the Web” by Tim Berners-Lee, which the page itself says was written for a possible book in around 1993 or 1994, and the article cites it three times. The page, fully read, says that the prototype worked as a browser after about a month and as an editor after another, which took the work to Christmas 1990, and the citation at line 24 is graded Partial, because the words “some time before” that line 24 quotes are from the page of footnote 1. The page says that in the summer of 1991 Tim Berners-Lee made the server and the clients available by FTP and mentioned them on the newsgroup alt.hypertext, and the citation at line 25 is graded Partial for its “August 1991”. The page names Bernd Pollermann, Nicola Pellow and the line mode browser, and Robert Cailliau, and the citation at line 26 is graded Supported.
1.7 Footnote 6, at line 59, cites “A Little History of the World Wide Web” of the World Wide Web Consortium, examined at W3C A Little History of the World Wide Web: Disagreements | Network, Not Protocol, for line 25. The page, fully read, records that in August 1991 the files were available on the net by FTP and were posted to alt.hypertext and to other newsgroups between the 6th and the 22nd of August. The citation is graded Supported.
1.8 Footnote 7, at line 60, cites “NeXT editor upgrade proposal” by Jean-François Groff on the site of the World Wide Web Consortium, for his involvement at line 26. The page, fully read, is signed JFG and proposes work on the NeXT editor, and it gives no date of its own. The citation is graded Supported. The same page says that the NeXT editor had been frozen since the summer of 1991.
1.9 Footnote 8, at line 61, cites “Welcome to info.cern.ch” of CERN, recorded as retrieved on 25 July 2010, for the claim at line 27 that Tim Berners-Lee considered the names The Mine of Information and The Information Mesh before publicly launching the browser in 1991. The live address, fully read, is now a page of four links that carries none of the claim, and the footnote names no archived copy. The copy archived on July 27, 2010, fully read, names both alternatives and says that the name WorldWideWeb was settled in May 1990, and it says nothing of a public launch in 1991. The citation is graded Partial, on a copy that the footnote does not name.
1.10 Footnote 9, at line 62, cites “The Nexus Browser” by Jim Boulton on Digital Archaeology, dated March 26, 2014, for the claim at line 28 that a new version of 1994 was renamed Nexus Browser to tell the software apart from the World Wide Web. The page, fully read, says the same. The citation is graded Supported.
1.11 Footnote 10, at line 63, cites “Web Browser History” by Bill Stewart on Living Internet for the claim at line 31 that Tim Berners-Lee and Jean-François Groff adapted the components of WorldWideWeb into a C version, creating the libwww API. The page, fully read, says that they ported the application to C in 1991 and 1992 and called the new browser libwww. The citation is graded Partial, because the source calls libwww a browser and not an API.
1.12 Footnote 11, at line 64, cites browsers.evolt.org for the claim at line 33 that several versions of the software are still available. The address now opens the index of the evolt.org Browser Archive, and its entry for WorldWideWeb (Nexus), fully read, lists files of versions 0.12 of August 1991, 0.15, 0.16, 1.0, 2.01 and 2.02 and a Nexus file of 1994. The citation is graded Supported.
1.13 Footnote 12, at line 65, cites a document that the article titles “History of Libwww”, at page 3, in the copy archived on September 16, 2009, for the claim at line 34 that Tim Berners-Lee considered the GNU General Public License for WorldWideWeb and chose the public domain. The document, nine pages, fully read, names no author, and its passage at page 3 concerns libwww: it says that he considered releasing libwww under the General Public License, heard that large companies would not use the web under any licensing issue, and released that code into the public domain. The citation is graded Partial, because the source’s subject is the library of common code and not WorldWideWeb.
1.14 Footnotes 13 and 14, at line 66 and line 67, cite the lot page of Sotheby’s for “Source Code for the WWW” and the BBC report of 30 June 2021 for the claim at line 35 that Sotheby’s held an auction for an NFT of the source code in 2021. Both pages, fully read, carry the claim, and both citations are graded Supported. The lot page names Tim Berners-Lee as the owner of the source code files, written between 3 October 1990 and 24 August 1991, and the BBC quotes him saying of the sale, “I’m not even selling the source code.”
2.0 None of the footnotes behind the article’s account of the public domain carries the release of WorldWideWeb, and the sources disagree on the dates of the name and of the first edition.
2.1 The article states the release of WorldWideWeb into the public domain at line 14, line 21, line 32 and line 34. Footnote 2 at line 14 and line 21 is the statement of 30 April 1993, which names three other programs, footnote 4 at line 21 gives no date and no release, line 32 carries no footnote, and footnote 12 at line 34 concerns the library of common code.
2.2 The sources date the name WorldWideWeb differently: the page of CERN of 2010 at footnote 8 says that the name was settled in May 1990, Robert Cailliau in the interview at footnote 3 dates the joint proposal titled World Wide Web to May 1990, and the page of the World Wide Web Consortium at footnote 6 says that Tim Berners-Lee made up the name WorldWideWeb for the program in October 1990.
2.3 The sources date the first edition differently: the infobox at line 7 gives 25 December 1990, Tim Berners-Lee at footnote 1 calls that date a whimsical label on an edition prepared before Christmas, and Jim Boulton at footnote 9 calls the first version the one from 1991.
2.4 In the interview at footnote 3, Robert Cailliau dates the first web server in the United States, at SLAC, to 12 December 1992, and the page of the World Wide Web Consortium at footnote 6 dates it to 12 December 1991.
3.0 Eight lines of the article carry no footnote, and the sources of other footnotes bear on five of them.
3.1 Lines 19, 20, 29, 32, 40, 43, 44 and 47 carry no footnote.
3.2 The interview at footnote 3 carries line 29 on the passive browsers and line 47 on the home page used as a page of bookmarks. The page of footnote 1 carries line 40 on the protocols, naming http, news, ftp and local file spaces, and line 44 on the functions Mark Selection and Link to Marked.
3.3 The statement of 30 April 1993 at footnote 2 bears on line 32, which says that the CERN directorate released the source code of WorldWideWeb into the public domain on that date, and the statement names three programs and not WorldWideWeb.
4.0 Of the 34 citations, 21 carry the sentence that cites them, 10 carry it in part, and 3 do not carry it.
4.1 Counted by footnote, footnotes 6, 7, 9, 11, 13 and 14 are graded Supported at every citation, footnotes 1, 3, 4, 5, 8, 10 and 12 are graded Partial at one or more citations, and footnote 2 is graded Not supported at both of its citations.
4.2 The three citations graded Not supported are the two citations of footnote 2 at line 14 and line 21 and the citation of footnote 4 at line 21, and all three concern the release of WorldWideWeb into the public domain.
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.
