RFC1833 "Internet Protocol, Version 6 (IPv6) Specification"[1] was published in Dec 1995, over 20 years ago. I think the transition took a lot longer than anyone anticipated, not least because so many people considered IPv4 was good enough to be getting on with. Only after the IPv4 address exhaustion occurred did many people finally understand that IPv6 was a necessity and not just something they could avoid by deploying another layer of NAT. The ISP I use was an early adopter of IPv6[2] and the first time I got an IPv6 address I remember wondering what all the fuss was about. For me as a consumer having an IPv6 address made almost no difference to my on-line experience. While that might sounds negative, it is actually a good thing, even several years ago IPv6 "just worked" for consumers. Today we see many ISPs deploying IPv6 on consumer connections. The Google statistics[3] show just how rapid the growth of IPv6 has been in the past few years. If you zoom in you can see the positive spikes which occur at weekends. These show that home and mobile connections tend to have a higher IPv6 penetration than office networks. 1: https://tools.ietf.org/html/rfc1883 https://tools.ietf.org/html/rfc1883 2: http://aa.net.uk/kb-broadband-ipv6.html http://aa.net.uk/kb-broadband-ipv6.html 3: https://www.google.com/intl/en/ipv6/statistics.html https://www.google.com/intl/en/ipv6/statistics.html
