Well the message I got earlier was the IPv6 will not fix
the NAT problem - true or not true?
Well, it won't fix the NAT problem in scenarios
where v6 is not deployed. But aside from the
other answers you've received so far, I've also
heard several people mention the need to support
something they call "address policy domains."
I don't understand why they need it and I don't
understand why an address policy domain couldn't
be described as, say, 22.214.171.124/28 and I don't
understand why it would *require* NAT, but it
is something I've heard on several occasions.
