> Clients can use 6to4, and will use it as soon as they become IPv6 only I think you mean NAT64. 6to4 is an IPv6-over-IPv4 tunneling mechanism, and thus would not be used by an IPv6-only host. > Servers will add support for IPv6 in due time, when admins get used to having it on their machines, and all network equipment supports it, and it stops breaking the sites for people on IPv4 only and people behind slower IPv6 tunnels. This is largely FUD. Network equipment has supported IPv6 for a while, IPv6 does not break sites for IPv4-only users, and there's no reason to believe that slow IPv6 tunnels are a significant problem. The performance and reliability myths were entirely debunked by the highly successful World IPv6 Day and World IPv6 Launch Day in 2011 and 2012, which is why forward-thinking companies like Google and Facebook have permanently enabled IPv6.
