What is rir?

RIR stands for Regional Internet Registry, which are organizations responsible for the allocation and registration of Internet number resources - such as IP addresses and autonomous system numbers - within a specific region of the world. There are five RIRs globally, each covering a specific geographic area:

1. ARIN (American Registry for Internet Numbers) - covers North America and parts of the Caribbean
2. RIPE NCC (Réseaux IP Européens Network Coordination Centre) - covers Europe, the Middle East, and Central Asia
3. APNIC (Asia-Pacific Network Information Centre) - covers Asia and the Pacific region
4. LACNIC (Latin America and Caribbean Network Information Centre) - covers Latin America and parts of the Caribbean
5. AFRINIC (African Network Information Centre) - covers Africa

These RIRs work to ensure the fair and efficient distribution of Internet number resources within their respective regions, as well as providing support and services to their members. They also play a key role in the global coordination of the Internet's numbering system.
