Regional Internet Registry or RIR — an organization that deals with addressing and routing issues on the Internet. Regional registrars deal with the technical side of the Internet: allocation of IP addresses, Autonomous system numbers, registration of reverse DNS zones, support for DNS root zones, and other technical projects.
RIR status is assigned by ICANN (Internet Corporation for Assigned Names and Numbers). All RIRs are organizations that exist on the contributions of their members. IANA delegates large amounts of Internet resources to the RIR, which the RIR reallocates to its members in accordance with its rules. All RIRs collectively form the NRO (Number Resource Organization), created to represent the interests of the RIR and global interaction.
To get detailed information about IP addresses, WHOIS services request relevant information from the servers ARIN, APNIC, AFRINIC, LANIC, RIPE, CNNIC, KISA/KRNIC and JPNIC.
Currently there are five RIRs:
- American Registry for Internet Numbers (ARIN) — for North America;
- RIPE Network Coordination Centre (RIPE NCC) — for Europe, the Middle East and Central Asia;
- Asia-Pacific Network Information Centre (APNIC) — for Asia and the Pacific;
- Latin American and Caribbean Network Information Centre (LACNIC) — for Latin America and the Caribbean;
- African Network Information Centre (AFRINIC) — for Africa and the Indian ocean region.
