About the NRO NC

About the NRO NC

The Number Resource Organization (NRO) is a coordinating body for the five Regional Internet Registries to formalise their cooperative efforts. While the NRO is composed of staff members of the different RIRs, the NRO NC is made up of three community representatives from each RIR region. Of the three people from each region, two are selected by the RIR community and a third is appointed by the RIR's Executive Board.


Under the terms of the MoU signed between the ICANN and the RIRs in October 2004, the NRO Number Council (NRO NC) also performs the role of the Address Supporting Organization Address Council (ASO AC).

The ASO is one of ICANN’s three Supporting Organizations (SOs). It reviews and develops recommendations on Internet Protocol (IP) address policy and advises the ICANN Board on policy issues relating to the operation, assignment, and management of IP addresses.


The ASO AC’s responsibilities include:

  • Undertaking a role in the Global Policy Development Process (GPDP) and ensuring that policy has been followed.
  • Defining procedures for the selection of individuals to serve on other ICANN bodies, in particular on the ICANN Board.
  • Selecting individuals to serve on ICANN’s Board in Seats 9 and 10.
  • Providing advice to the ICANN Board on Internet number resource allocation policy in conjunction with the ASO/NRO.
  • Developing procedures for conducting business in support of their responsibilities, in particular for the appointment of an ASO AC Chair and definition of the Chair’s responsibilities.

ASO AC Teleconferences

The ASO AC meets on the first Wednesday of each month by teleconference. These meetings are open to observers.
