Release of data

Release of 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.

Do you need access to data?

There are, however, exceptions. 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.
