Attribute status
Mandatory
Attribute must be included in the object. Failure to do so will result in errors.
Attribute | Description |
---|---|
as-set | The name of a set of aut-num objects. The as-set attribute may take two forms:Hierarchical as-setA hierarchical as-set attribute consists of as-set names and AS numbers separated by colons ‘:‘. There must be at least one ‘set-name‘ within the hierarchical name that starts with ‘AS-‘.
<origin-as-number>:AS-CUSTOMERS <origin-as-number>:AS-PEERS EXAMPLE AS1:AS-CUSTOMERS Non-hierarchical as-set Non-hierarchical as-set objects may no longer be created after the implementation of prop-151, though some existing non-hierarchical as-set objects will remain in place. A non-hierarchical attribute must begin with ‘AS-‘.
EXAMPLE AS-UNALLOCATED ASNs |
descr | A short description related to the object’s purpose.
EXAMPLE Peers for AS1 ExampleNet |
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.
|
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.
|
mnt-by | Lists a registered ‘mntner’ used to authorize and authenticate changes to this object.
|
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 |
members | Explicitly lists members of the as-set. Members of an as-set can be: AS numbers; or AS sets
|
mbrs-by-ref | The identifier of a registered ‘mntner’ object that can be used to add members to the as-set indirectly.
|
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 | Sometimes there is a hierarchy of maintainers. In these cases, mnt-lower is used as well as mnt-by. |
Generated
Attribute value is generated by the database.
Updating
You can update this object in the Whois updates page in MyAPNIC.
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 as-set objects
The as-set object allows you to group AS numbers with similar properties.
For example, instead of referring to many individual AS numbers in the import and export attributes of the aut-num object, you can refer to a single as-set object.
For example, by using the following as-set object:
as-set AS1:AS-CUSTOMERS members: AS2, AS3, AS4, AS5
… instead of using this long import statement:
import: from AS2 accept AS2 import: from AS3 accept AS3 import: from AS4 accept AS4 import: from AS5 accept AS5
… you could replace it with this simple import statement:
import: from AS1:AS-CUSTOMERS accept AS1:AS-CUSTOMERS
If you use automated tools used to configure routers, the aut-num objects associated with the as-set object will be returned, and all individual routes that originate from the AS numbers will be injected into your configuration files.
