DNS64 is a DNS64 server technique used to enable IPv6-only hosts to access IPv4-only resources. It works by intercepting DNS queries for IPv4 addresses that are not directly resolvable on the IPv6 network. When a query for an IPv4 address is received, the DNS64 server synthesizes an IPv6 address from the IPv4 address. This synthesized IPv6 address is then returned to the client. This synthesized address typically has a specific prefix, known as the "well-known prefix," which indicates that it is an IPv4-translated address.
The DNS64 server then relies on a NAT64 (Network Address Translation 64) translator to map the synthesized
DNS64 is a crucial component in facilitating IPv6 adoption by providing a backward-compatible mechanism for accessing
