Reverse DNS delegations resource guide

Definition

Reverse DNS delegations allow applications to map to a domain name from an IP address. Reverse delegation is achieved by use of the pseudo-domain names in-addr.arpa (IPv4) and ip6.arpa (IPv6).

Please note, APNIC registers only reverse delegations and is not involved in the domain name registration system.
