NRO Number Council


The Number Resource Organization (NRO) Memorandum of Understanding (MoU), signed in October 2003, called for the creation of a Number Council. The MoU reads, in part:

"The NRO Number Council shall be responsible for the provision of advice to the Executive Council concerning the ratification of proposed global IP number resource allocation policies.

"The NRO Number Council shall act as a point of consultation to external entities on proposed global IP number resource policies, addressing questions that may be raised concerning such policy proposals, maintaining a dialogue with the entity and the RIRs concerning these proposals as required.

"The NRO Number Council shall develop procedures in an accessible, open, transparent and documented manner for conducting business in support of their responsibilities and submit these procedures to the Executive Council for approval."

In October 2004, the NRO and ICANN signed the Address Supporting Organization (ASO) MoU, which dictated that the NRO Number Council fulfill the role of ICANN's ASO Address Council (ASO AC). The ASO AC, consisting of members appointed or elected to the NRO Number Council, will continue to function as a role of ICANN as required in ICANN's Bylaws.

Address Supporting Organization (ASO)

ASO Formation and Function

The Address Supporting Organization (ASO) is one of three Supporting Organizations called for in the ICANN Bylaws to be "formed through community consensus." The purpose of the ASO is to review and develop recommendations on IP address policy and to advise the ICANN Board on these matters.
In July 1999, the three currently existing Regional Internet Registries (APNIC, ARIN, and RIPE NCC) submitted a proposal to form the ASO on the basis of a Memorandum of Understanding. ICANN accepted this proposal on 26 August 1999.

The ASO was subsequently formed on 19 October 1999, when the MoU was signed by representatives of the RIRs and ICANN, during the ARIN IV Public Policy Meeting in Denver. LACNIC and AFRINIC also signed the ASO MoU upon their recognition as RIRs.

Each Regional Internet Registry (RIR) has three members on the Number Council.
