ASO is the acronym for Address Supporting Organization, which is one of the supporting organizations that was formed, according to ICANN's bylaws, through community consensus. The main objective of the ASO is to review and develop Internet Protocol recommendations, address policy, and advise the ICANN Board.
It was created in 1999 and the members of ASO represent the Address Council. Each RIR appoints 2 members through their regional policy forums, and another member comes from each RIR's executive board.
In July, 1999, when the three Regional Internet Registries which existed then, APNIC, ARIN, and RIPE NCC submitted their proposal for the creation of the ASO on the basis of the Memorandum of Understanding; which allows for the creation of a body such as the ASO as an extension of the NRO.
ICANN approved the proposal at its meeting in Chile, and the ASO was subsequently created in October, 1999, when the representatives of APNIC, ARIN, RIPE NCC and ICANN signed the MoU. LACNIC was later recognized as the 4th RIR and it signed the agreement on October 30th, 2002. The Memorandum of Understanding was modified in October, 2004, and signed by ICANN and the NRO, which signed on behalf of all the RIRs. When ICANN decided to recognize AfriNIC as the fifth global RIR the representatives of AfriNIC signed the MoU, and it was incorporated as the 5th NRO member.
