Registration

Registration

IP WHOIS provides registration information for IP address blocks, revealing who owns and operates specific IP addresses. Unlike domain WHOIS (website ownership), IP WHOIS focuses on network infrastructure.

History

The RIR system was established in the 1990s to manage growing demand. IANA allocated the final IPv4 blocks to RIRs in 2011, leading to IPv6 adoption and IPv4 address trading markets.
