Regional Internet Registries (RIRs)

Regional Internet Registries (RIRs) manage and distribute IP address allocations and Autonomous System Numbers (ASNs) within specific geographic regions. They ensure fair distribution, maintain database accuracy, and support internet infrastructure growth. The five RIRs—ARIN, RIPE NCC, APNIC, LACNIC, and AFRINIC—coordinate with IANA to maintain global IP address management.
