Whois Domain Lookup
Identify the owner, registrar and expiration date of any domain.
Whois lookup: who's behind a domain?
Whois is the public registry of all domain names. It contains owner information, creation and expiration dates, the registrar used and DNS servers. Think of it as the land registry of the internet.
Available information
- Owner — name, organization, email (if not privacy-protected)
- Key dates — creation, last update, expiration
- Registrar — where the domain is registered
- DNS servers — servers handling domain resolution
How to use it
- Enter the domain name to look up
- Get all available Whois information
When to use Whois
- Identify site owners — for partnerships or abuse reports
- Verify domains before buying — check history, age and registrar
- Monitor your domain — ensure expiration date is current (expired domain = SEO disaster)
Combine with Domain Age Checker and Domain Authority. Read our practical Whois guide.
FAQ
Why is Whois information hidden?
Since GDPR (2018), most registrars automatically mask personal data for European owners. Owners can also enable paid "Whois privacy." This is legal and common — it doesn't mean the site is suspicious.
