About ICANN
ICANN Lookup provides registration data for domains using the RDAP protocol, the authoritative replacement for classic WHOIS, free from the domain system's coordinator. Anyone verifying domain ownership or expiry starts with the official source. In practice, it is the kind of single-purpose tool people keep bookmarked for a recurring job, and users usually compare it on speed, limits, privacy handling, and whether it works without registration.
