RIR Comparative Policy Overview
September 30, 2005

PDF Version

 

(version 2005-09)

The goal of this document is to provide a comparative overview of policies across the RIR system. It is not a policy statement by the RIRs, but serves as a reference for the Internet community. While this document was accurate on the date of publication (September 30, 2005), it may be outdated by subsequent policy implementations. The official policy documents can be found at the respective web sites of the RIRs. This is a public document that will be reviewed and revised through the co-ordinated efforts of the RIRs.

For more information, refer to the AFRINIC, APNIC, ARIN, LACNIC, and RIPE NCC web sites.

Category

Policy

Comment

APNIC

Eligibility

ASNs may be obtained directly from APNIC as a member or non-member. The ASN obtained directly is portable. ASNs may also be obtained indirectly, through a LIR who 'sponsors' the request. In this event, the ASN is non-portable.
Criteria need to be met in both cases, that is:
An organisation is eligible if it a) is multihomed; and b) has a single, defined routing policy that is different from its providers' routing policies. An organisation will also be eligible if it can demonstrate that it will meet the above criteria upon receiving an ASN (or within a reasonably short time thereafter).

 

AFRINIC
ARIN
LACNIC
RIPE NCC

 

Eligibility

Policies for AS number assignments are aligned with the guidelines contained in RFC1930. Verify that a network will have a unique routing policy or that it will be a multihomed site before assigning an AS Number.

In RIPE region ASNs cannot be requested directly. An application must be submitted to the RIPE NCC via an existing LIR.
