Whois Lookup — Domain Registration and IP Whois Tool
Look up WHOIS records for any domain name or IP address. See registration dates, registrar, name servers, owner information, and expiry date. Free, no signup.
Parsed summary will appear here.
How to use
- 1.Enter a domain name (e.g. google.com) or an IP address (e.g. 8.8.8.8).
- 2.Click Lookup — results appear in both raw JSON and a parsed summary.
- 3.The raw panel shows the full RDAP or WHOIS response.
- 4.The parsed panel shows key fields: registrar, dates, nameservers.
Notes
- —This tool prefers RDAP (JSON-native) and falls back to classic WHOIS if needed.
- —Returned fields vary by registry and TLD. Some records are redacted for privacy (GDPR).
- —IP lookups show block allocation info (owner of the range), not end-user identity.
- —Internationalized domains are normalised to ASCII (Punycode) before lookup.
- —Requests are rate-limited. Wait a moment and try again if you hit the limit.
