Attribute status
Mandatory
Attribute must be included in the object. Failure to do so will result in errors.
Attribute | Description |
---|---|
aut-num | The Autonomous System number. |
as-name | A descriptive name used to identify an Autonomous System (AS). |
Org |
Points to an existing organisation object representing the entity that holds the resource.
|
sponsoring-org |
Points to an existing organisation object representing the sponsoring organisation responsible for the resource.
|
admin-c |
The NIC-handle of an on-site contact ‘person’ object. As more than one person often fulfills a role function, there may be more than one admin-c listed.
|
tech-c |
The NIC-handle of a technical contact ‘person’ or ‘role’ object. As more than one person often fulfills a role function, there may be more than one tech-c listed.
|
abuse-c | References an abuse contact. This can only be a ROLE object containing an “abuse-mailbox:” attribute. Making this reference will remove any query limits for the ROLE object. These ROLE objects are considered to include only commercial data.
|
mnt-by |
Lists a registered ‘mntner’ used to authorize and authenticate changes to this object.
|
mnt-irt | The identifier of a registered ‘mntner’ object used to provide information about a Computer Security Incident Response Team (CSIRT). |
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 |
source | The database where the object is registered. |
Optional
Attribute may be deleted from the object. To delete an optional attribute you must also remove the attribute from the object template. Failure to do so will result in errors.
Attribute | Description |
---|---|
country |
Two letter ISO 3166 code of the country or economy where the admin-c is based. Please use UPPERCASE letters. EXAMPLE country: WF |
member-of | Identifies ‘as-set’ objects of which this aut-num object is intended to be a member. An aut-num may be useful to include in an ‘as-set’ if your network maintains a number of Autonomous Systems or wishes to include its routes in an upstream provider’s routing information. To be included in an ‘as-set’, the ‘ as-set’ object must:
Note: do not include an ‘as-set’ in this attribute if this aut-num is explicitly mentioned in the ‘as-set’ object’s members attribute. Attempts |
import |
The inbound IPv4 routing policy of the AS.
import: from <peering-1> [action <action-1>] accept <filter> For more information, see RFC 2622 – Routing Policy Specification Language (RPSL), section 6.1 |
mp-import |
The inbound IPv4 or IPv6 routing policy of the AS.
mp-import: [protocol <protocol-1>] [into <protocol-2>] afi <afi-list> from <peering-1> [action <action-1>] accept (<filter>|<filter> except <importexpression>| <filter> refine <importexpression>) For more information, see RFC 4012 – Routing Policy Specification Language next generation (RPSLng), section 4.5. |
export |
The outbound routing policy of the AS.
export: from <peering-1> [action <action-1>] announce <filter> For more information, see RFC 2622 – Routing Policy Specification Language (RPSL), section 6.2. |
mp-export |
This attribute performs the same function as the export attribute above. The difference is that mp-export allows both IPv4 and IPv6 address families to be specified.
mp-export: [protocol <protocol-1>] [into <protocol-2>] afi <afi-list> to <mp-peering-1> [action <action-1>] announce <mp-filter> For more information see RFC 4012 – Routing Policy Specification Language next generation (RPSLng), section 4.5. |
default |
The peer network the AS will use for as a default, that is, when the AS has no more-specific information on where to send the traffic.
default: to <peering> [action <action>] [networks <filter>] For more information, see RFC 2622 – Routing Policy Specification Language (RPSL), section 6.5. |
mp-default |
This attribute performs the same function as the ‘default’ attribute above. The difference is that mp-default allows both IPv4 and IPv6 addresses to be specified.
mp-default: [protocol <protocol-1>] [into <protocol-1>] afi <afi-list> to <mp-peering> [action <action-1>] announce <filter> For more information, see RFC 4012 – Routing Policy Specification Language next generation (RPSLng), section 4.5. |
remarks | Information about the object that cannot be stated in other attributes. May include a URL or email address. |
notify |
The email address to which notifications of changes to this object will be sent.
|
mnt-lower | The identifiers of registered ‘mntner’ objects used to control the creation of hierarchically named ‘as-set’ objects that use the name of the aut-num object. If no mnt-lower attribute is listed, mnt-by is referred to when authorizing hierarchically named ‘as-set’ objects. |
mnt-routes | The identifier of a registered ‘mntner’ object used to control the creation of ‘route’ objects that refer to this AS number in the route’s origin attribute. |
Generated
Attribute value is generated by the database.
Instances of attribute allowed
Single |
Attribute must appear only once in the object. |
Multiple |
Attribute may appear multiple times in the object. For example, you may wish to include more than one admin-c attribute. |
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. |
Using aut-num objects
- Use aut-num objects to help configure your network’s routers.
Aut-num objects, in combination with other routing related objects can be used to describe your routing policy in a compact form. This can help your network identify routing policy errors and omissions more easily than by reading long
configuration files. - Use automated tools, such as IRRToolset, to retrieve information from the aut-num objects to create
router configuration files for different architectures.
Configuration files produced this way should be much less prone to errors than manually configured routers. - Aut-num objects can also be used by network administrators to debug network problems.
As part of the APNIC Whois Database quality improvement project, in early November 2018, all APNIC delegated ASNs will be protected by APNIC’s maintainer to avoid the aut-num object being deleted accidentally. APNIC Members can continue to update their aut-num object in MyAPNIC and contact the APNIC Helpdesk if they wish to update some protected attributes such as: as-name, descr, country and org.
Please take a minute to review your ASN record and make an update if any information is outdated.
As part of this project, APNIC will be deprecating the old process of using the ‘auto-dbm@apnic.net’ email to update the aut-num object. We recommend you use MyAPNIC to update your whois records.
APNIC will keep Members updated of progress.
