WHOIS Lookup
Retrieve registration and ownership information for domains or IPs.
The WHOIS tool queries public WHOIS servers and displays the raw data in a simplified form (Simple mode) or as JSON (Advanced mode).
Things you can see
- Registrar and registration/expiry dates
- Name servers
- Status codes (clientTransferProhibited, etc.)
WHOIS data can be rate-limited or partially redacted depending on TLD and privacy regulations.
