Global Policy Proposal for Autonomous System Numbers - Background Report | (Proposal to change the date for full transition from 16-bit to 32-bit ASNs)

Global Internet Number Resource Policies are defined by the ASO MOU - between ICANN and the NRO - as "Internet number resource policies that have the agreement of all RIRs according to their policy development processes and ICANN, and require specific actions or outcomes on the part of IANA or any other external ICANN-related body in order to be implemented". Attachment A of this MOU describes the Development Process of Global Internet Number Resource Policies, including the adoption by every RIR of a global policy to be forwarded to the ICANN Board by the ASO, as well as its ratification by the ICANN Board. In this context, the ICANN Board adopted its own Procedures for the Review of Internet Number Resource Policies Forwarded by the ASO for Ratification.

Among other features, these Procedures state that the Board will decide, as and when appropriate, that ICANN staff should follow the development of a particular global policy, undertaking an “early awareness” tracking of proposals in the addressing community. To this end, staff should issue background reports periodically, forwarded to the Board, to all ICANN Supporting Organizations and Advisory Committees and posted at the ICANN Web site.

At its meeting on 27 August 2009, the Board resolved to request tracking of the development of a Global Policy Proposal for "IANA Policy for Allocation of ASN Blocks to Regional Internet Registries", under discussion in the addressing community. The status overview presented below is compiled in response to this request and will be further updated as developments proceed, for information to ICANN entities and the wider community. This is the third issue of the tracking of this policy.

Status Overview

The current Global Policy for Autonomous System Numbers, ASNs, removes the policy distinction between 16-bit and 32-bit ASNs on 1 January 2010. The new Global Policy Proposal moves that date to 1 January 2011.

The proposal was first introduced in RIPE on 27 May 2009, in ARIN on 29 May 2009, in LACNIC on 1 June 2009, in APNIC on 13 July 2009 and in AfriNIC on 28 August 2009. It has now been adopted in all RIRs; RIPE, ARIN, APNIC, LACNIC and AfriNIC.

On 6 August 2009, the ASO AC recognized the proposal as fulfilling the formal requirements as a candidate for a Global Policy.

Once adopted by all the RIRs, i.e. ARIN, AfriNIC, LACNIC, RIPE and APNIC, the proposal will be handled by the NRO EC and the ASO AC according to their procedures before being submitted to the ICANN Board for ratification.

The table below outlines the steps taken within each RIR for the current proposal. Hyperlinks are included for easy access.
