When you register your domain, default DNS (Domain Nameservers)
settings are used. Your web hosting provider can give you their primary
and secondary DNS information and you can change the default settings to
those of your web host. The DNS information usually looks something
Primary Hostname- ns1.examplehostname.com
Primary IP- 184.108.40.206
Secondary Hostname- ns2.examplehostname.com
Secondary IP- 220.127.116.11
To change DNS information
Please allow 24 - 48 hours for your change to propagate throughout the Internet.
For .DK domains, you can only specify nameservers that are known at the registry. To use any other nameservers, you must first submit the application form found here: http://www.dk-hostmaster.dk/index.php?id=200. When your application has been processed and your nameservers have been approved, you will receive a notification by email.
Note: The registry charges a fee to register nameservers.
