Whois Lookup
Find a domain's registration details, owner and expiry date instantly.
With the Whois lookup tool you can instantly see any domain's registration details: its owner, registration and expiry dates, name servers and registrar. Use it to check whether a domain is available before you buy it, to see when your own domain expires, or to find out who registered a domain.
A Whois lookup is also known as a domain lookup: it shows who a domain belongs to, when it was registered and when it expires. If the domain you looked up is free you can register it right away, and you can check your domain's DNS settings with our NS lookup and A record lookup tools.

Frequently asked questions
Common questions about Whois lookups and domain names.
What is Whois?
Whois is the protocol used to query a domain's registration details. A Whois lookup shows the domain's owner, registration and expiry dates, name servers and registrar.
Is the Whois lookup free?
Yes. The SunucuPARK Whois lookup is completely free, and you can look up as many domains as you like.
Why can Whois details be hidden?
Because of the GDPR and other privacy rules, some registrars hide Whois details (Whois privacy). In that case proxy details are shown instead of personal information.
How can I find out when my domain expires?
Type your domain into the Whois lookup to see its registration and expiry dates. We recommend renewing it before it expires.
How can I register an available domain?
If the Whois lookup shows that a domain is not registered, you can register it with SunucuPARK right away. We register .com, .net, .org and .com.tr domains at affordable prices.
Why does the name server (NS) information matter?
NS details show which DNS servers your domain is connected to. A wrong NS record can stop your website and email from working.
Is a domain lookup the same as a Whois lookup?
In practice, yes. A “domain lookup” usually means checking whether a domain is free and who owns it, and that information comes from a Whois query. For unregistered domains our tool shows “Available” and takes you straight to registration.
