Can Large Scale NAT Save IPv4?
Julie188 writes "The sales pitch was that IPv6, with its zillions of new IP addresses, would eliminate the need for network address translation altogether. But Jeff Doyle, one of the guys who literally wrote the book on IPv6, suggests that not only will NAT be needed, but it will be needed to save IPv4 at the tipping point of IPv6 adoption. 'I've written previously that as we make the slow — and long overdue — transition from IPv4 to IPv6, we will soon be stuck with an awkward interim period in which the only new globally routable addresses we can get are IPv6, but most public content we want to reach is still IPv4. Large Scale NAT (LSN, also known as Carrier Grade NAT or CGN) is an essential tool for stretching a service provider's public IPv4 address space during this transitional period.'"
at work we use NAT behind a whole public class B and it work great. But as a customer I would not put up with it. I want to act as a server not only a dumb host. So please stop the carrier grade nating madness.

Except for all the people still on XP, which has no native IPv6 support...
Has too. You just need to enable it: http://ipv6int.net/systems/windows_xp-ipv6.html
err windows xp does have ipv6 support but its not installed by default (in fact has had it since XP sp2)
now it may not have all the bells and whistles of say Vistas support (if anything can be supported by Vista) but you should at least be able to get an IP and get online.

I don't know where you have been getting your predictions. It is pretty certain that IANA is going to run out of space about the middle of next year.
We have 14 /8's left in the IANA free pool, we use up almost 2 /8's every month.
Are you betting on the ipv4 space usage magically decreasing ( right when everyone will start freaking out about getting their last allocations )?
I am a lawyer and this constitutes legal advice and I shall indemnify you against any losses arising from taking it.
Support for XP has stopped, it's an old OS.
Windows XP is supported until 2014 if you keep up with service packs.
