ICANN has announced a Public Comment Period relating to the implementation of GPP-IPv4-2011: Global Policy Proposal for Post Exhaustion IPv4 Allocation Mechanisms by the IANA.

The ICANN Board announced ratification of GPP-IPv4-2011 on 17 May 2012. The proposal had reached consensus in all Regional Internet Registry (RIR) regions and was reviewed by the NRO EC and the ASO AC prior to transmission to the ICANN Board on 13 March 2012.

The policy provides a mechanism for the redistribution of IPv4 address space returned to an IANA-managed pool. Once active, address space in this Recovered IPv4 Pool can be allocated, in equal shares, to the five RIRs.

The IANA reports that the RIRs have so far returned approximately 1¼ of /8s of address space in almost 150 prefixes.

The Comment Period will remain open until 23:59 (UTC) 25 October 2012. The purpose of this consultation is to gather input on the most appropriate way to make these changes for the different users of the IANA IPv4 address registries.
