You will be surprised: China and India are on IPv6. Oh, and maybe
Japan, for IPTV networks.
You see, the problem is real. By 2011 or 2012, public IPv4 address
space will be exhausted. Maybe Europe and North America will still be
fine (plenty of IPv4 addresses), but the real pain is that the IPv6
Internet does not talk to IPv4 Internet. So we may end up with a
"split-brain" Internet.
Double NAT (IPv6 to IPv4 and back) seems to be a pain the ass, because
there are not enough large boxes to handle ISP traffic. And I think
that content providers will go for dual stacking (servers talking both
IPv4 and IPv6).
Another problems are: lack of access equipment able to handle IPv6,
lack of application support for IPv6 (this is more like an enterprise
problem, anyway), network equipment not being able to process IPv6 in
hardware, licensing (feature set needed to support IPv6) and so on.
In Europe, the only success story I have heard of is free.fr.
I wish I knew more, but I don't.
