Release of data

This page lists the data available from DK Hostmaster and what you need to do if you want access to the data.

Available data

DK Hostmaster has collected all data concerning registered .dk domain names in a database we call the WHOIS database. It contains details about registrants, proxys, name servers, domain name creation date etc. Find publicly available data here.

According to the Danish Domain Names Act, DK Hostmaster is obliged to provide a publicly available database so that you, as a user of the Danish namespace, can see who has registered a given .dk domain name.

Non-accessible data

There are, however, exceptions. These include individuals with name and address protection in the Civil Registration System. These people are protected by the Danish Act on Processing of Personal Data and, therefore, we do not display their details.

Furthermore, we do not show billing information for a .dk domain name. We believe that this is a matter between registrant and payer.

Do you need access to data?

You must contact us if you need data that is not publicly available, for example for a legal dispute. To enable us to assess your request, you must specify which details you need and how you intend to use them.

If we do not find that your request is adequate, we will ask you for further details. In all other instances, we will process your request for data based on current legislation, our terms of business and best practice.

If you are a third party to a domain name and would like access to data, we will only be able to release them if you prove a legal interest in the data. If you request data on behalf of a registrant, please include a power of attorney when you submit your request.

We cannot help you with domain names with a suffix other than .dk.

If you need data relating to a .dk domain name, please send your request to
