Regional Internet registry
Template:Short description Template:Infobox organization Template:Internet A regional Internet registry (RIR) is an organization that manages the allocation and registration of Internet number resources within a region of the world. Internet number resources include IP addresses and autonomous system (AS) numbers.

The regional Internet registry system evolved, eventually dividing the responsibility for management to a registry for each of five regions of the world. The regional Internet registries are informally liaised through the unincorporated Number Resource Organization (NRO), which is a coordinating body to act on matters of global importance.<ref>Template:Cite web</ref>
There are five regional registries:
- The African Network Information Centre (AFRINIC) is based in Ebene, Mauritius and serves all of Africa.<ref name="afrinic">Template:Cite web</ref>
- The American Registry for Internet Numbers (ARIN) is based in Chantilly, Virginia, United States and serves Antarctica, Canada, the United States, and some Caribbean countries and territories.<ref name="arin">Template:Cite web</ref>
- The Asia Pacific Network Information Centre (APNIC) is based in Brisbane, Australia and serves East, South and Southeast Asia and Oceania.<ref name="apnic">Template:Cite web</ref>
- The Latin America and Caribbean Network Information Centre (LACNIC) is based in Montevideo, Uruguay and serves Latin America as well as some Caribbean countries.<ref name="lacnic">Template:Cite web</ref>
- Réseaux IP Européens Network Coordination Centre (RIPE NCC) is based in Amsterdam, Netherlands and serves Central and West Asia, Europe, and Russia.<ref name="ripe">Template:Cite web</ref>


Internet Assigned Numbers Authority
Regional Internet registries are components of the Internet Number Registry System, which is described in IETF RFC 7020,<ref>Template:Cite ietf</ref> where IETF stands for the Internet Engineering Task Force. The Internet Assigned Numbers Authority (IANA) delegates Internet resources to the RIRs who, in turn, follow their regional policies to delegate resources to their customers, which include Internet service providers and end-user organizations.<ref>Template:Cite journal</ref> Collectively, the RIRs participate in the Number Resource Organization (NRO),<ref name="nro">Template:Cite web</ref> formed as a body to represent their collective interests, undertake joint activities, and coordinate their activities globally. The NRO has entered into an agreement with ICANN for the establishment of the Address Supporting Organisation (ASO),<ref name="aso">Template:Cite web</ref> which undertakes coordination of global IP addressing policies within the ICANN framework.
Number Resource Organization
The Number Resource Organization (NRO) is an unincorporated organization uniting the five RIRs.<ref name="nro" /> It came into existence on October 24, 2003, when the four existing RIRs entered into a memorandum of understanding (MoU) in order to undertake joint activities, including joint technical projects and policy coordination. The youngest RIR, AFRINIC, joined in April 2005.
The NRO's main objectives are to:
- Protect the unallocated IP number resource pool.
- Promote and protect the bottom-up policy development process of the Internet.
- Serve as a focal point for the Internet community to provide input on the RIR system.
Address Supporting Organization
The NRO is formally affiliated with ICANN in its role as ICANN's Address Supporting Organization (ASO). According to the ASO website, its purpose is "to review and develop recommendations on Internet Protocol (IP) address policy and to advise the ICANN Board on policy issues relating to the operation, assignment, and management of IP addresses."<ref>Template:Cite web</ref> The ASO is made of up of representatives from each of the five regional internet registries. It nominates two members of the ICANN board of directors. Its members make up the Address Council.
Local Internet registry
A local Internet registry (LIR) is an organization that has been allocated a block of IP addresses by a RIR, and that assigns most parts of this block to its own customers.<ref>Template:Cite web</ref> Most LIRs are Internet service providers, enterprises, or academic institutions. Membership in a regional Internet registry is required to become a LIR.
