Year Month and date (if available) Entity type Entity name Stage Details
1993 September Standard IPv6 Project/working group creation The Internet Engineering Task Force (IETF) creates a temporary, ad-hoc IP Next Generation (IPng) working group, led by Allison Mankin and Scott Bradner.[1]
1995 January Standard IPv6 Recommendations The IPng working group produces its list of recommendations for the IP next generation protocol, published as RFC 1752.[1]
1996 November Operating system Linux IPv6 experimental The first network code related to IPv6 is introduced in the Linux kernel 2.1.8 by Pedro Roque, based on the BSD API.[2][3][4]
1998 Project/working group creation The KAME project starts as a subproject of the WIDE Project. It is a joint effort of six organizations in Japan which aimed to provide a free IPv6 and IPsec (for both IPv4 and IPv6) protocol stack implementation for variants of the BSD Unix computer operating-system. The project would conclude in March 2006.[5]
1998 December Standard IPv6 standard Protocol draft The draft IPv6 protocol standard is published by the Internet Engineering Task Force (IETF) as RFC 2460.[6]
2000 October Operating system Linux Project/working group creation The USAGI project is created to improve the quality and production-readiness of the Linux IPv6 stack.
2003 May 3 Statistics Cisco 6lab IPv6 statistics Statistics start Cisco's 6lab has data on IPv6 prefixes by country starting around this time.[7]
2005 June 18 Operation system Linux IPv6 full support Linux kernel 2.6.12 is released, with the "experimental" label dropped on its level of IPv6 support.[8][3][9][4]
2007 October Statistics Eggert's IPv6 statistics Statistics start Lars Eggert's statistics on the percentage of websites with IPv6 support had data going back to this time.[10]
2008 May 13 Website Google IPv6 experimental Google announces that an IPv6 version of its search website is available at ipv6.google.com.[11]
2008 September 4 Statistics Google IPv6 statistics Statistics start Google's IPv6 statistics are available starting this date.[12]
2010 February 5 Website YouTube IPv6 active Video hosting website YouTube confirms that it now supports IPv6.[13][14] This had been noticed by commentators on February 1, before the confirmation.[15]
2011 January 11 ISP Comcast IPv6 access support Internet Service Provider (ISP) Comcast activates its first 25 IPv6-enabled users in the Littleton, Colorado area using Apple computers. Comcast uses a Native Dual Stack configuration that supports both IPv4 and IPv6, using DOCSIS 3.0.[16][17]
2011 April RFC 6146, describing the NAT64 standard, and RFC 6147, describing the DNS64 standard, are published.[18][19]
2011 May 3 Hosting service Linode IPv6 hosting support Server hosting service Linode begins offering native IPv6 support.[20]
2011 May 24 Hosting service Amazon Web Services IPv6 hosting support Amazon Web Services offers IPv6 support for its Elastic Load Balancers (ELBs) in US East and Ireland. All load balancers in these regions have publicly routable IPv6 addresses in addition to their IPv4 addresses.[21]
2011 June 8 World IPv6 Day happens. On this day, major websites, including Google services, Facebook, Yahoo, and Bing, activate IPv6. The vast majority of devices are expected to be unaffected: they will either use IPv6 or fallback to IPv4.[22] The day is deemed successful.[23] See World IPv6 Day and World IPv6 Launch Day for more.
2012 April 24 IPv6 is available over APN for the entire T-Mobile US network.[24][25] This follows an update in January that T-Mobile is testing IPv6 on select devices.[26] T-Mobile's transition would be the subject of a later case study.[27]
2012 May 4 Statistics Cisco 6lab IPv6 statistics Statistics start Cisco 6lab statistics on web content with IPv6 support start around this time.[28]
2012 June 6 World IPv6 launch occurs. This is a permanent version of the IPv6 launch that occurred on the previous World IPv6 Day in 2011, instead of the 24-hour version used that day.[29] See World IPv6 Day and World IPv6 Launch Day for more.
2014 June 17 Hosting service DigitalOcean IPv6 hosting support Server hosting service DigitalOcean begins offering native IPv6 support.[30][31]
2014 July 22 Comcast reports that 100% of its broadband mobile network now supports IPv6.[32]
2016 August Facebook reports that over 50% of its traffic from the four major U.S. mobile networks is now over IPv6. Similarly, Akamai reports that over 50% of requests to dual-stacked sites on Akamai from the four major U.S. mobile networks is now over IPv6.[33]
2017 January 25 Hosting service Amazon Web Services IPv6 hosting support Amazon Web Services begins offering IPv6 support for EC2 instances in virtual private clouds (VPCs) in 15 regions, and Application Load Balancers in 9 regions.[34] An initial announcement around this appears to have been made on December 1, 2016.[35]
2017 July 14 Standard IPv6 standard Protocol official The IPv6 standard is made official in RFC 8200, obsoleting the draft standard (RFC 2460) published in December 1998.[36]
2017 September 20 Hosting service Google Cloud Platform IPv6 hosting support Google Cloud Platform announces general availability (GA) for IPv6 global load balancing.[37]
