Registering your Reverse Delegations with APNIC
Important
Ensure that the zone has been loaded on your nameserver and associated secondaries before filling out this form. The diagnostic script uses both UDP and TCP to verify the nameservers (may cause timeouts if you block TCP port 53).In the case of /16 level delegations (ie, X.X.in-addr.arpa rather than /24 delegations, X.X.X.in-addr.arpa), APNIC can secondary the zone from your name servers in order to increase the visibility of your reverse delegations if required. Contact dns-admin@apnic.net for further information.
AUNIC reverse delegations
Beginning 1 June 2001, AUNIC delegations (203.0.0.0 to 203.63.255.255) also use this form. For more information on the migration of network records from the AUNIC to APNIC database, please see AUNIC to APNIC Migration . The superseded AUNIC specific form resides here. If you need help registering a reverse delegation for space previously registered by AUNIC, please contact helpdesk@apnic.net.
Detailed setup guides exist for setting up your IN-ADDR.ARPA (IPv4) and the IP6.arpa (IPv6) domains. These guides describe how to create appropriate in-addr.arpa or ip6.arpa zone files and how to get them running on your nameservers. These steps must be completed before you use the following forms.
