> I don't see the point of NAT64 though, it dosen't seem to have any advantages over dual-stack and CGN and seems to require more infrastructure and introduce more flakiness (proxying DNS). Having IPv6-only edge infrastructure seems to be more of a geek-cred thing than a practical benefit.
Until you can run a IPv6 only system and get real use out of it, everyone is going to need to continue to run, and be subject to the limitations of IPv4
As a result, I see NAT64 as being the tool that has the potential to break the IPv4 lock-in by allowing IPv6 only devices to communicate with the real-world
Waiting for all servers to switch to IPv6 before you get clients to fix is even worse than trying to kill off Internet Explorer 6
