  • An administrative contact (admin-c) must be someone who is physically located at the site of the network.

  • A technical contact (tech-c) must be a person responsible for the day-to-day operation of the network, but does not need to be physically located at the site of the network.
auth Defines the authentication scheme to be used to link resources (aut-num, inetnum, inet6num) to this irt object. Authentication options available are:


auth: PGPKEY-80FFBF15

Note : WHOIS currently also supports CRYPT-PW and MD5, but they will be deprecated soon.

For information on how to use these authentication options see:

arrow-blue Authentication options for mntner objects

mnt-by Lists a registered ‘mntner’ used to authorize and authenticate changes to this object.

  • A ‘mntner’ object is a database object used to authorize updates to the APNIC database.
  • When your database details are protected by a ‘mntner’ object, then only persons with access to the security information of that ‘mntner’ object will be able to change details.
  • In the web interface, the mnt-by attribute contains a link to the specified ‘mntner’.
last-modified It is a time stamp that is generated by the system to reflect when the object was last modified.

last-modified: 2018-08-30T07:50:19Z

Attribute search status

Primary key
Primary keys distinguish an object from all other objects in the database. To update a primary key, you must delete the entire object and them create a new object with the updated information.
Lookup key
Attribute can be queried in the database to return the object.  Please note, however, that a lookup key does not uniquely identify an object.
Inverse key
Attribute can be used when performing an inverse query using the -i flag. For example, the query

-i mntner <MNTNER-NAME>

will return all objects with the specified maintainer in the mnt-by attribute.
