IPv6 has its problems, but running out of addresses is not one of them. For those of us worried about abuse management, the problem is the opposite, even the current tiny sliver of addresses is so huge that techniques from IPv4 to map who's doing what where don't scale.
Well, in IPv4... NAT broke it, because networks implementing 1:many NAT could no longer easily identify what host was responsible for abuse.
I realize that's a problem in theory, in practice it's not because it's still rare to have interestingly different hosts behind a single NAT.
CGN should solve that and convert theory to practice quite effectively. Owen
