Creating and registering a new domain object

Before you start

  1. Have you registered all customer assignments relevant to the zone you wish to register?
    APNIC will only accept reverse delegations for assigned space. Unassigned space cannot be registered as a domain object.
  2. Have you set up your reverse zone?
    You must create a reverse zone before your request for a reverse delegation can be processed.


    Ensure that the zone has been loaded on your nameserver and associated secondaries (if any) 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).

  3. Is your IPv4 reverse zone on a bit boundary?
    APNIC only permits delegations of /8, /16, and /24 for IPv4 reverse delegations. For example, to register a /15, you need to register two /16 objects. To register a /20, you would need to create sixteen /24 reverse domain objects.
  4. Are you registering an IPv6 zone? delegations, like delegations, must be made on nibble boundaries. A /32 allocation is on the nibble boundary. The nearest nibble boundary for a /35 is between bits 35 and 36. Therefore, a /35 delegation must be split into two /36 delegations and registered as two separate domain objects.

How to register a new domain object

  1. To register a new domain object, you must either use MyAPNIC or submit your request for a new reverse domain object by copying the template in the text-based form and emailng it to
  2. The APNIC parser will check the domain object you submit to verify all details are correct.The parser also checks that the referenced DNS servers are authoritative and correctly return this domain’s information. If any information provided in the domain object cannot be validated by the parser, your request will fail and you will be notified of the relevant problem.
  3. Your request will be sent to APNIC staff, who will manually create the domain object.To protect against the unauthorized creation of reverse domain objects in the APNIC Whois Database, APNIC maintains authority over the creation of new reverse domain objects. This means that when you create a new reverse domain object, the parser will send you a hierarchical authorization failed message. APNIC staff will manually enter your reverse domain object into the APNIC Whois Database and give you authority over the maintainer object.
  4. Your reverse domain object will become visible on the Internet when the zone files in the APNIC nameserver are updated.The APNIC zone files are updated every two hours.
