About the NRO

The Number Resource Organization (NRO) is the coordinating mechanism for the five Regional Internet Registries (RIRs).

The RIRs – AFRINIC, APNIC, ARIN, LACNIC and the RIPE NCC – ensure the fair and equitable distribution of Internet number resources (IPv6 and IPv4 addresses and Autonomous System (AS) Numbers) in their respective regions.

The NRO exists to protect the unallocated Internet number resource pool, foster
open and consensus-based policy development, and provide a single point of contact for communication with the RIRs.

For more information, please visit the About the NRO page.

About the Regional Internet Registries

Regional Internet Registries regions

Regional Internet Registries (RIRs) are nonprofit corporations that administer and register Internet Protocol (IP) address space – IPv4 and IPv6 – and Autonomous System (AS) Numbers within a defined region. RIRs also work together on joint projects.

RIR Region
AFRINIC Africa, portions of the Indian Ocean
APNIC Asia Pacific
ARIN Canada, many Caribbean and North Atlantic islands, and
the United States
LACNIC Latin America and the Caribbean
RIPE NCC Europe, the Middle East, parts of Central Asia

Hot Topic IPv4 Depletion and IPv6 Adoption

As of 3 February 2011, the central pool of available IPv4 addresses managed by the Internet Assigned Numbers Authority (IANA) has been depleted.

The five Regional Internet Registries (AFRINIC, APNIC, ARIN, LACNIC and the RIPE NCC) will continue to allocate IPv4 address space to their members in accordance with their community-based regional policies until their pools of available IPv4 addresses are depleted. It is difficult to predict when the RIRs will run out of IPv4 addresses. The RIRs will continue to allocate IPv6 addresses as they have since 1999.

IPv6 is a newer numbering system designed to account for future Internet growth. Many decision makers don’t realise how many devices require IP addresses – mobile phones, laptops, servers, routers, the list goes on.

Please see the NRO IPv4 Depletion and IPv6 Deployment FAQ to learn more.

Hot Topic Internet Governance

Since the early stages of the Internet, the NRO and each individual Regional Internet Registry (RIR) have actively cooperated with a wide range of stakeholders to ensure the future growth and continued stability of the Internet. The NRO is committed to continuing this cooperation, and engages with many governments and related global institutions with an interest in the development of the Internet.

The NRO has been active in, and continues to participate in the following Internet Governance related forums and committees:

Hot Topic Resource Certification

A resource certificate created by one of the five RIRs is a verifiable digital statement that an Internet number resource (a block of IPv4 or IPv6 addresses, or an Autonomous System Number) has been registered by that RIR. In 2011, the five Regional Internet Registries will deploy a system of Internet resource certification. What is it and what does it mean for you?
