Carrier Trick To Save IPv4 Could Help Spammers 124
Julie188 writes "As public IPv4 addresses dwindle and carriers roll out IPv6, a new problem has surfaced. We have to move through a gray phase where the only new globally routable addresses we can get are IPv6, but most public content we want to reach is still IPv4. Multiple-layers of NAT will be required to sustain the Internet for that time, perhaps for years. But use of Large Scale NAT (LSN) systems by service providers will cause problems for many applications and one of them is reputation filtering. Many security filtering systems use lists of public IPv4 addresses to identify 'undesirable' hosts on the Internet. As more ISPs deploy LSN systems, the effectiveness of these IPv4 filtering systems will be hurt."

NAT is fine for people who only make outgoing connections; i.e. the passive internet consumer.
It's hell for the rest of us, but hey, since when did the massive media conglomerates ever have the techies' interests at heart?

remember apps both client and server have to support v6, not just the OS
Really badly written programs.
Seriously. I've written stuff in C with the sockets API that is IPv4/v6 agnostic. It's easy to do; there is no excuse for not implementing it.

My ISP (AAISP) actively encourage IPv4 address exhaustion AFAICT.
It's really not in ISPs interests to conserve IPs at this point. The more IPs they can get out of the RIRs now the more IPs they will have to reuse for more lucrative customers later.

I understand the point you are trying to make, and I agree with you. I just have to be pedantic and point out that currently, for WoW accounts that have been tampered with, it doesn't matter that the activity was on the same IP address.
If it did matter, there would be a lot of guys with neglected girlfriends that would be unable to get their characters restored.
