About the NRO

The Number Resource Organization (NRO) was established in 2003 as a coordinating body for the world’s five Regional Internet Registries (RIRs).

The RIRs manage the distribution of Internet number resources (IP address space and Autonomous System Numbers) within their respective regions.


The mission of the NRO is to actively contribute to an open, stable and secure Internet, through:

  • Providing and promoting a coordinated Internet number registry system.
  • Being an authoritative voice on the multi-stakeholder model and bottom-up policy process in Internet governance.
  • Coordinating and supporting joint activities of the RIRs.

Executive Council

The CEOs/Directors of the five RIRs form the NRO Executive Council (NRO EC). The positions of Chair, Vice Chair/Secretary and Treasurer rotate annually.

Coordination Efforts

The NRO is a coordination point for joint RIR activities and projects, including Resource Certification (RPKI), global RIR statistics reports, global Internet governance activities and global policy coordination.

The NRO does not manage or perform any of these activities directly. Instead, the NRO facilitates several Coordination Groups in the areas of Communications, Engineering, Registration Services and Executive leadership to support collaboration across the RIR system.

NRO Secretariat

A permanent NRO Secretariat provides coordinated support for both NRO and ASO activities.
