This document specifies how to discover the NAT64 pools in use and DNS servers providing DNS64 service to the local Nodes. The discovery made via SRV records allows the assignment of priorities to the NAT64 pools and DNS64 servers. It also allows Nodes to have different DNS providers than NAT64 providers while providing a secure way via DNSSEC validation of provided SRV records. This way, it provides DNS64 service regardless of DNS operator and DNS transport protocol.
