Cisco points out that many other transition techniques are possible, and NAT-PT (Network Address Translation - Protocol Translation) should not be used when other, more "native" options exist ...
NAT64 - Wikipedia
https://en.wikipedia.org/wiki/NAT64NAT64 is an IPv6 transition mechanism that facilitates communication between IPv6 and IPv4 hosts by using a form of network address translation (NAT). The NAT64 gateway is a translator between IPv4 and IPv6 protocols, for which function it needs at least one IPv4 address and an IPv6 network segment comprising a 32-bit address space. The "well-known prefix" reserved for this service is 64:ff9b::/96.
