Board adopts final IPv4 Global Policy Proposal. 


Raimundo Beca introduced a resolution:

Whereas, the ASO Address Council has forwarded a codification of existing global policies for allocation of IPv4 address blocks from IANA to the Regional Internet Registries (RIRs), affirming that the Policy had been approved in accordance with the policy development process adopted and specified by the ASO MOU.

Whereas, on 18 February 2005, ICANN's Board adopted a resolution preliminarily adopting the proposed policy as a valid codification of current procedures, and directed the President to continue to follow the policy in the performance of the IANA function.

Whereas, the proposed IPv4 Global Allocation Policy was posted for public comment on 9 March 2005, with the stated goal of finalizing adoption of the policy barring any substantial objection from the community or constituent bodies, at the ICANN meetings in Mar del Plata, Argentina, in April 2005.

Whereas, the Board has considered the public comments that were submitted to the forum and determined that existing procedures adequately address the issues that were raised, and no objection was raised by the Security and Stability Advisory Committee or other ICANN advisory bodies.

Resolved (05.19), the proposed IPv4 Global Allocation Policy is adopted, and the President is directed to continue to follow the policy in the performance of the IANA function.

Demi Getschko requested statistics on actual IPv4 usage. Ray Plzak of the NRO was in the audience and gave the Board an overview indicating that 40 to 45% of all available IPv4 address space remained available to be issued by IANA to the RIRs. Mr. Plzak stated that a variety of recent studies have estimated that these unallocated addresses should last for 10, 20 or 40 years, based on current usage and conservation policies. Mr. Plzak also noted that Geoff Huston and others had created an animation showing the rate at which IPv4 addresses and AS numbers had been consumed over the past 25 years: "BGP, the movie" (58MB) - <>.

The resolution was moved by Raimundo Beca, seconded by Mouhamet Diop, and approved (as amended above) unanimously by the Board, 14-0.
