  Ah, right, that one with all the ALGs. Kinda NAT64's ancestor, though I have no idea of the evolution/development process. I don't believe this ever worked at scale, even if it is pretty much NAT64. Particularly the part where IPv4 hosts can reach IPv6 systems with the NAT-PT tracking through DNS what is given out in A records is "a bit much".
