Regional Internet registry
Organization responsible for managing network numbering
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.[1]
As of 2005, there are currently five regional registries:
- The African Network Information Centre (AFRINIC) is based in Ebene, Mauritius and serves all of Africa.[2]
- The American Registry for Internet Numbers (ARIN) is based in Chantilly, Virginia and serves Antarctica, Canada, the United States, and some Caribbean countries and territories.[3]
- The Asia Pacific Network Information Centre (APNIC) is based in Brisbane, Australia and serves East, South and Southeast Asia and Oceania.[4]
- The Latin America and Caribbean Network Information Centre (LACNIC) is based in Montevideo, Uruguay and serves Latin America as well as some Caribbean countries.[5]
- Réseaux IP Européens Network Coordination Centre (RIPE NCC) is based in Amsterdam, Netherlands and serves Central and West Asia, Europe, and Russia.[6]
