ASO

ASO is the Address Supporting Organization (ASO) of ICANN.

The purpose of the ASO is to review and develop recommendations on Internet Protocol (IP) address policy and to advise the ICANN Board.

The ASO was formed on 19 October 1999, when the MoU was signed by representatives of APNIC, ARIN, and RIPE NCC and ICANN. A new Memorandum of Understanding between ICANN and the Number Resource Organization, on behalf of the Regional Internet Registries, was signed on 21 October 2004.
