NAT64 and DNS64 on Linux: Tayga and BIND 9 Configuration

Tue, 15 Apr 2025 10:00:00 -0500

NAT64 lets IPv6-only clients reach IPv4-only servers: DNS64 synthesizes an AAAA record inside a NAT64 prefix such as 64:ff9b::/96, and a NAT64 gateway translates packets sent to that prefix into IPv4. This page gives a working Tayga gateway and BIND 9 resolver first, then the high-availability, monitoring and prefix planning material for larger networks.
