Whois Domain Lookup

Find out information about domains and their owners

WHOIS Result:

What is Whois?

Whois allows you to retrieve information about domains and their owners.

From a technical point of view, Whois is a protocol. The data is stored in a distributed database system and can be queried with Whois. The Whois database is kept up to date by the domain registries.

The GDPR has changed the Whois significantly

Since the GDPR, the publication of personal data is prohibited. This has also significantly changed the Whois.

Previously, data such as name, address and email were visible for every domain. Today, these are only visible in some cases.

Which information can I find out?

Basically, the available data differs from domain extension to domain extension and whether the holder is a private person or a company.

For most endings, you can find out:

  • The domain status (e.g. if it is already in use)
  • The name servers used
  • The responsible registrar
  • Partial data from the holder (more on this below)
  • Registration, expiry and update dates

In the case of .de domains, only the name servers can be viewed publicly.

Owner data: For most other endings, the name, address, e-mail address and telephone number of the company can be viewed. If the domain holder is a private person and EU citizen, the contact details of the current registrar are displayed.

A domain is being used illegally, what can I do?

If a domain is being used illegally or improperly, you or an official authority can request the holder data from the responsible domain registry.

How does the lookup work?

The lookup can be started easily via our Whois Lookup. To do this, you can simply enter the domain name in the search field.
