About this tool
Check WHOIS IP is a static, browser-based client. Check WHOIS IP queries RDAP — the structured successor to WHOIS — live from your browser against the public RDAP service.
It shows registration dates, status codes and nameservers; most registrant fields are redacted under privacy rules, which RDAP reflects honestly. The lookup is sent from your browser to the public RDAP service; this site has no backend and never receives it, and a network connection is required.
