WHOIS

WHOIS is a query-response protocol used to look up registration information for domain names, IP addresses, and autonomous systems. A WHOIS lookup reveals the [[registrant]], registration and expiration dates, [[nameserver|nameservers]], and the [[registrar]] of record.

Example

Running a WHOIS lookup on example.com shows it was registered on August 14, 1995, and is managed by IANA.
