[arin-discuss] Trying to Understand IPV6

[Randy Carpenter]

Everyone arguing that NAT is a good thing should have been involved a decade ago when it was decided that IPv6 was not going to have NAT.  The NAT argument is over.

I wish we would all stop arguing about these issues, and the hardware manufacturers would get some things on the market. We are running dangerously close to needing IPv6 for user expansion, and we have no way to deploy it.
