Regional Internet registry
A regional Internet registry (RIR) is an organization that manages the allocation and registration of Internet number resources within a particular region of the world. Internet number resources include IP addresses and autonomous system (AS) numbers.
The regional Internet registry system evolved over time, eventually dividing the world into five RIRs:
- The African Network Information Center (AFRINIC) serves Africa
- The American Registry for Internet Numbers (ARIN) serves Antarctica, Canada, parts of the Caribbean, and the United States
- The Asia-Pacific Network Information Centre (APNIC) serves East Asia, Oceania, South Asia, and Southeast Asia
- The Latin America and Caribbean Network Information Centre (LACNIC) serves most of the Caribbean and all of Latin America
- The Réseaux IP Européens Network Coordination Centre (RIPE NCC) serves Europe, Central Asia, Russia, and West Asia
Internet Assigned Numbers AuthorityEdit
Regional Internet registries are components of the Internet Number Registry System, which is described in IETF RFC 7020. 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. Collectively, the RIRs participate in the Number Resource Organization (NRO), 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), which undertakes coordination of global IP addressing policies within the ICANN framework.
Number Resource OrganizationEdit
The Number Resource Organization (NRO) is an unincorporated organization uniting the five RIRs. 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, liaison activities and policy co-ordination.
AFRINIC, which was officially created in April 2005, joined on April 25, 2005.
The main aims of the NRO are to:
Local Internet registryEdit
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. Most LIRs are Internet service providers, enterprises, or academic institutions. Membership in a regional Internet registry is required to become a LIR.
