Now correct me if I'm wrong, but isn't some kind of NAT/PAT going to be required to join the IPv4 and IPv6 domains in all foreseeable futures? If so, aren't we going to have to deal with these issues in any case?
No, we need to move forward with IPv6 on all levels in order to reduce the need for these solutions. Reduce, yes. Remove, no. Without a global cutoff date for the IPv6 transition, it's not like IPv4 is going to disappear overnight. Furthermore, without any IPv4/IPv6 translation, the first IPv6 only networks are going to be awfully lonely.
Joining the IPv4/IPv6 domains doesn't work out all that well and a dependency on doing so is broken in a number of ways, many of which are documented in the draft. We agree that IPv4/IPv6 domain interoperability is broken, but it's not like we can ignore the issue. So, unless I'm very much mistaken, the NAT/PAT issues are going to have to be dealt with. Or do you propose an alternative solution?
Please note that this is not an anti-IPv6 stance. To me it looks like the problems plaguing NAT444 need to be solved just to make IPv4 and IPv6 co-exist. Perhaps not the very same problems, but similar NAT/PAT problems in any case. Please do tell me I'm wrong. Bonus points for explaining why I am wrong or how the IPv4/IPv6 thing is to be solved without NAT/PAT. - Zed
