Number Resource Organization

The Number Resource Organization (NRO) is a coordinating body for the five Regional Internet Registries to formalise their cooperative efforts.

NRO logo 2The NRO exists to:

  • Protect the unallocated Number Resource pool,
  • Promote and protect the bottom up policy development process, and
  • Act as a focal point for Internet community input into the RIR system.


History of the NRO

On 24 October 2003, the four existing RIRs – APNIC, ARIN, LACNIC and the RIPE NCC – entered into a Memorandum of Understanding (MoU) with ICANN to form the NRO. Once AfriNIC was incorporated in April 2005 it signed the MoU and joined the NRO.

The NRO Number Council (NC)

Under the terms of the MoU signed between the ICANN and the RIRs in October 2004, the NRO Number Council (NRO NC) now performs the role of the Address Supporting Organization Address Council (ASO AC). The NRO NC is made up of three community representatives from each RIR region.
