WHOIS domain lookup

Enter domain name or IP to look up WHOIS information


What is Whois?

With the Whois Lookup service, you will receive publicly available information about any registered domain name. The Whois Information is retrieved from a standardized informational source, the so called Whois database. This service may help you in order to look up who owns a given domain respectively, whether it is still available or not.

Why is the Whois Lookup useful?

The Whois Lookup may help you in order to find out who owns or manages a domain. The Whois Service gives you direct access to available contact information of the respective domain owner. This can be useful in order to get in touch with the domain owner, if there are technical issues with the domain or if any legal rights have been violated. In addition to that, the Whois Lookup can be helpful if you intend to buy a domain name that has already been registered and you plan to submit an offer to the current domain owner.

Why is there no detailed Whois Information for some domain names?

Depending on the registry that is responsible for the domain name you are interested in, you may receive different kinds of information using the Whois Lookup. The registry defines which records will be kept in the Whois database. Thus, it may happen that for some domain names no data or only a limited amount of information can be displayed. Furthermore, some domain owners use private domain registration where the personal data is kept confidential, hence these information cannot be accessed using the Whois Lookup.

Can everyone see my information?

The short answer is, yes. Generally, whenever you register a domain name, it is required to transmit specific personal data to the respective registry. These requirements may vary slightly from registry to registry. However, it is necessary that these personal data are publicly available for two reasons. Firstly, it offers the possibility to find out who is in charge of a specific domain from a technical perspective in case of technical issues. Secondly, it helps to identify a contact person in the event of infringement of third-party rights. Regardless of the requirements stated above, data protection is the top priority at 1&1 and we assure you that your data is safe with us.
