Network Dictionary – Address Family Translation

Address Family Translation (AFT) terms used to describe replacing headers and addresses of one family of IP (IPv4, IPv6) with headers and addresses from another IP family, in an IP packet.

Compare this with Network Address Translation (NAT) which describes addresses translation within one IP family e.g. private to public IPv4 (you should never consider using NAT66, it has no future in the Internet)

Note: AFT will require Name to Address Family Translation where AAAA DNS6 records and A DNS4 records must also be translated (otherwise known as DNS64 and DNS46)
