Personally I hate NAT. But I currently work in a large enterprise environment and NAT is suprisingly popular. I came from a service provider background and some of the attitudes I've discovered towards private addresses in enterprise environments are quite surprising. Aside for the usual proponents of using NAT to hide your internal address infrastructure (which security always seem to insist upon) quite a popular design rule of from seems to be "Only carry public addresses on the public Internet and only carry private addresses on your private network" :-|
If an Enterprise doesn't have a great deal for IP addresses that need to be routed on the public internet, and they thing that NAT is a _good_ design choice, it seems to me that they don't have a great deal of pressure to move to IPv6.
In fact, and call me crazy, but I can't help but wonder how many enterprises out there will see IPv6 and its concept of "real IPs for all machines, internal and external!" and respond with "Hell No." Anyone got any numbers for that? I'm happy to admit I don't. :) Adrian
