Enter a domain name

The domain you enter is sent to our server, which asks the domain registry for its public records and returns them to you. Results are saved for a few minutes. Many owners hide their personal details, so contact information is often not shown.

How to use it

The whois search tool is great to find out if a domain name has been registered or is available.

Enter the domainEnter the domain name you would like to search for into the text field above.
Check itClick on ‘Check Domain’ for the program to check a database to see if the domain is registered.
Read the resultOnce the results have been returned, you will see information if it is registered, such as the registrar, key dates and name servers.

Making sense of the result

Check the expiry date

A domain that is close to its expiry date may be renewed, or it may be about to drop and become available. Expired domains often stay locked for a while first.

Read the statuses

Statuses such as “client transfer prohibited” are normal protections. “pending delete” or “redemption period” mean the domain is expiring and not yet free to register.

Name servers show the host

The name servers point to the company that runs the domain’s DNS, which often tells you who hosts the website or email.

Frequently asked questions

Where does the information come from?

From the public records kept by the domain registry for each extension. Where available the tool uses RDAP, the modern replacement for Whois, and otherwise it falls back to a classic Whois query.

Why can’t I see the owner’s name or email?

Since privacy rules such as GDPR, most registries and registrars hide personal details by default. You will normally see the registrar and dates, but not who owns the domain.

It says a domain is available. Is that certain?

It means the registry has no record of it. A few names can still be reserved or restricted and cannot be bought, so the registrar will give the final answer when you try to register it.

Can I look up a subdomain or a full web address?

Yes. You can paste a full address such as https://www.example.com/page. The tool removes the extras and, for a subdomain, shows the registered domain it belongs to.

Does it work for every extension?

It covers most extensions, including .com, .net, .org, .nl and .uk. A few registries do not publish a public lookup or format their answers in their own way. When that happens the tool shows the raw answer so you can still read it.

Why am I asked to wait?

Registries limit how fast they answer, and this tool limits how many domains one visitor can check each minute. Wait a moment and try again.
