ipv6

ipv6 does not route data, it is a routed protocol. not a routing protocol. CCNA 101 — Preceding unsigned comment added by 64.60.167.78 (talk) 22:01, 7 February 2014 (UTC)

IPv6 HIstory

The history of the Internet begins with the development of electronic computers in the 1950s. Initial concepts of packet networking originated in several computer science laboratories in the United States, Great Britain, and France. The US Department of Defense awarded contracts as early as the 1960s for packet network systems, including the development of the ARPANET (which would become the first network to use the Internet Protocol.) The first message was sent over the ARPANET from computer science Professor Leonard Kleinrock's laboratory at University of California, Los Angeles (UCLA) to the second network node at Stanford Research Institute (SRI). Packet switching networks such as ARPANET, Mark I at NPL in the UK, CYCLADES, Merit Network, Tymnet, and Telenet, were developed in the late 1960s and early 1970s using a variety of communications protocols. The ARPANET in particular led to the development of protocols for internetworking, in which multiple separate networks could be joined into a network of networks. Access to the ARPANET was expanded in 1981 when the National Science Foundation (NSF) funded the Computer Science Network (CSNET). In 1982, the Internet protocol suite (TCP/IP) was introduced as the standard networking protocol on the ARPANET. In the early 1980s the NSF funded the establishment for national supercomputing centers at several universities, and provided interconnectivity in 1986 with the NSFNET project, which also created network access to the supercomputer sites in the United States from research and education organizations. Commercial Internet service providers (ISPs) began to emerge in the late 1980s. The ARPANET was decommissioned in 1990. Private connections to the Internet by commercial entities became widespread quickly, and the NSFNET was decommissioned in 1995, removing the last restrictions on the use of the Internet to carry commercial traffic. Since the mid-1990s, the Internet has had a revolutionary impact on culture and commerce, including the rise of near-instant communication by electronic mail, instant messaging, voice over Internet Protocol (VoIP) telephone calls, two-way interactive video calls, and the World Wide Web with its discussion forums, blogs, social networking, and online shopping sites. The research and education community continues to develop and use advanced networks such as NSF's very high speed Backbone Network Service (vBNS), Internet2, and National LambdaRail. Increasing amounts of data are transmitted at higher and higher speeds over fiber optic networks operating at 1-Gbit/s, 10-Gbit/s, or more. The Internet's takeover of the global communication landscape was almost instant in historical terms: it only communicated 1% of the information flowing through two-way telecommunications networks in the year 1993, already 51% by 2000, and more than 97% of the telecommunicated information by 2007.[1] Today the Internet continues to grow, driven by ever greater amounts of online information, commerce, entertainment, and social networking.

All of the above is irrelevant to IPv6 history - it's cut and paste from history of the Internet. As the prior text said, the history of IPv6 needs to have more from RFC 1752. TcomptonMA 22:55, 25 March 2014 (UTC) — Preceding unsigned comment added by TcomptonMA (talk • contribs)

Date of IPv6 "conception"

While it should be relatively straightforward, reality is IPv6 was conceived incrementally in the IETF "IPng Task Force"; resulting protocol is amalgam of several proposals with different dates of origin; makes 'date of conception' nearly impossible to set. One possible solution (if a date is really desired in the sentence) would be phrasing as 'IPv6 was selected in January 1995...', citing RFC 1752 which provides an overview of the development process.

IPv4 is still here!?!?!?!?!?!?

I went on get.youripaddress.com and saw an IPv4 address. Maybe the problem is that my computer doesn't use IPv6...

Please help. ElliottBelardo (talk) 11:58, 18 March 2013 (UTC)

Late reply, but still relevant: that site doesn't support IPv6 so you can't use it to tell whether you have it or not.--Jasper Deng (talk) 20:06, 26 April 2014 (UTC)

Why so many addresses?

I think that there should be a way to more easily explain this concept: whereas IPv4 has 8 bits per quad, IPv6 has 16 bits per "unit" (for lack of a better word), and instead of 4 parts, it has 8. It just seems like this information is missing, even though it's obvious (or should be). Hires an editor (talk) 04:29, 31 August 2014 (UTC)

Unless you go back to classful addresses in IPv4, and even there it's marginal, the number of "units", or the size of those "units" is not really meaningful. There are 32 or 128 address bits, the "units" you're describing are just about how they're commonly written. Rwessel (talk) 15:43, 2 September 2014 (UTC)

IPv6 example in "blurb"

While 2001:0db8:85a3:0042:1000:8a2e:0370:7334 is more representative of a "real" IPv6, I think it would be more communicative to use something like 1234:5678:90AB:CDEF:1234:5678:90AB:CDEF as it make it very easy to decode the length and makes for easy mnemonics. 83.89.33.37 (talk) 10:29, 26 December 2014 (UTC)

The individual parts are not discussed much, if at all, making any mnemonic quality rather pointless. And a plausibly real address has some advantages too. Rwessel (talk) 05:00, 27 December 2014 (UTC)
