Explanation

NAT64 is a mechanism for IPv4-to-IPv6 transition and IPv4-IPv6 coexistence. Together with DNS64, the primary purpose of NAT64 is to allow an IPv6-only client to initiate communications to an IPv4-only server.NAT64 can also be used for IPv4-only clients initiating communications with IPv6-only servers using static or manual bindings.
