WHOIS Lookup

See who a domain is registered with, when it was registered and expires, and whether it is locked against theft, straight from the registry.

Enter a domain or hostname. Pasted URLs and internationalized names work too.

What this checks

  • Registrar, registration date and domain age
  • Expiry date, with a warning in the last 30 days
  • Transfer lock, the main protection against domain theft
  • Every status code, explained in plain English
  • Nameservers and DNSSEC as recorded at the registry

How to read the results

Pass
The check succeeded based on the observed responses.
Warning
Works now, but is risky, unusual or worth reviewing.
Fail
A problem was observed directly in the responses.
Inconclusive
Not enough evidence — for example a server did not respond.
