Internet Assigned Numbers Authority (IANA) Policy For Allocation of IPv4 Blocks to Regional Internet Registries
On 3 September 2004 the ASO Address Council forwarded a new IPv4 policy concerning IANA allocations of IPv4 address to Regional Internet number Registries to the ICANN board for action, affirming that the policy had been approved in accordance with the four RIR's local policy development processes.
This new policy will replace prior operational agreements between IANA and the RIRs governing IPv4 allocations only.
On 18 February 2005 the ICANN Board preliminarily adopted the proposed policy as a valid codification of current procedures, and directed staff to continue to follow the policy in the performance of the IANA function, pending final approval by the Board after a public comment period. This policy is now available for a 21 day public comment period.
