NAT-PT translates between what address types?

This describes traditional IPv4 Network Address Translation (NAT) or Port Address Translation (NAPT), which translates private IPv4 addresses to public IPv4 addresses.

NAT-PT (Network Address Translation - Protocol Translation) is an IPv6 transition mechanism that enables communication between IPv6-only networks and IPv4-only networks. It performs a stateless translation of IP addresses and headers between IPv4 and IPv6 protocols, allowing devices from different IP versions to communicate as if they were on the same protocol.

This is a vague description that does not accurately represent the primary function of NAT-PT, which focuses on IP address protocol translation.

This would be a form of NAT within IPv6, but NAT-PT specifically refers to the translation between IPv4 and IPv6 protocols.
