WHOIS Lookup
Uses RDAP (modern WHOIS) via rdap.org. CORS-restricted: many TLD registries are not RDAP-enabled.
About this tool
WHOIS Lookup is a single-purpose utility on instant.tw, a free toolbox of calculators, converters, generators, and quick lookups. Everything works in your browser — nothing is uploaded, nothing is stored on a server unless explicitly noted.
