Attributes of as-block objects

as-block template

To view the as-block template, see APNIC Whois Database object templates.

The following describe the mandatory and optional attributes in an as-block object.

Note: Attributes marked with an asterisk (*) now support four-byte AS number syntax. For more information see the ASN resource guide.

Attributes	Description
as-block*	A range of AS numbers delegated to a Regional or National Internet Registry. The AS numbers in the range are subsequently assigned by the registry to members or end-users in the region. Information on individual AS numbers within an as-block object are stored in the appropriate Internet Registry's whois database.
admin-c	The NIC-handle of an on-site contact person object. In the web interface, the admin-c field contains a link to that person object the NIC-handle belongs to.
tech-c	The NIC-handle of a technical person object. In the web interface, the tech-c field contains a link to that person object the NIC-handle belongs to.
mnt-by	The identifier of a registered mntner object used for authorisation and authentication.
changed	The email address of who last updated the database object and the date it occurred. The changed attribute is not a network contact address, as it merely records who made the most recent change to the registration information. All APNIC addresses will initially record an APNIC address in this attribute, as APNIC creates the first database object.
source	The name of the database from which the data was obtained.

Attribute	Description
descr	Description of the Internet Registry delegated the range of AS numbers shown in the as-block.
country	Two letter ISO 3166 code of the country or economy where the admin-c is based. Details of codes are specified in ISO 3166.
remarks	Information on the registry that maintains details of AS numbers assigned from the as-block. Also includes where to direct a whois client to find further information on the AS numbers.
notify	The e-mail address to which notifications of changes to the object should be sent.
mnt-lower	The identifier of a registered mntner object used to authorise the creation of aut-num objects within the range specified by the as-block. If no mnt-lower is specified, the mnt-by attribute is used for authorisation.
