1) It needs *much less* IPv4 addresses (in the NAT64) for the same number of customers.

I cannot see how this is even possible. If I use private space internally to the CGN, then the available external space is the same and the internal customers are the same and I can do the same over sub ratio under both circumstance. Tell me how the math is different.

Because NAT64 implies DNS64, which avoids NATing any dual stack service. This makes a major difference today. Bjørn
