Tools/WHOIS Lookup

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 tool 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.

Frequently asked questions

How do I check when a domain expires?
Enter the domain above. The lookup reads the expiry date straight from the registry and warns when fewer than 30 days remain.
Can I find out who owns a domain?
Usually not. Since GDPR, most registries and registrars hide the owner's name and contact details. The lookup shows the registrar, which can forward messages to the owner.
What is the difference between WHOIS and RDAP?
RDAP is the modern replacement for WHOIS. It returns the same registration data in a structured, standard format, and ICANN made it the official source for generic domains in January 2025.
What does clientTransferProhibited mean?
It is the registrar's transfer lock: the domain cannot be moved to another registrar until the lock is removed. It is normal and recommended.
