IP addresses are allocated by five Regional Internet Registries (RIRs) — ARIN, RIPE NCC, APNIC, LACNIC, and AFRINIC — each responsible for a different geographic region.
IP WHOIS reveals which organization owns an IP block, the network range, autonomous system number (ASN), and administrative contacts responsible for the address space.
