> Combine that with most users being happy and comfortable with 1 IP address and there was no mass market appeal for IPv6 hardware or software. The mass market appeal for IPv6 is the fact that we do not have enough IPv4 to actually give one internet connection a unique IP. CGNAT is getting ever more present in the marketplace as a result of this. Major providers are rolling out IPv6. eg in the USA, several major cable/fibre providers provide v6, several mobile networks provide IPv6 using things like 464xlat. It's the same in the UK - BT for example provide IPv6 on consumer internet connections, EE (a major phone carrier) provide v6 and use 464xlat to provide v4 connectivity to handsets. India and Germany are further ahead still, generally. Google's IPv6 stats are a good indicator of just how much v6 is in use now: https://www.google.com/intl/en/ipv6/statistics.html#tab=ipv6-adoption https://www.google.com/intl/en/ipv6/statistics.html#tab=ipv6...
