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 like this:
Primary Hostname- ns1.examplehostname.com
Primary IP- 22.214.171.124
Secondary Hostname- ns2.examplehostname.com
Secondary IP- 126.96.36.199
To change DNS information
- Click Manage, and log in to your account.
- Beside the domain whose DNS you want to change, click DNS.
- Replace the existing information with the information provided by your web hosting company (you may omit the IP addresses, as they are optional).
- Click Save. Your new DNS information is automatically entered, if it is verified to be valid.
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.
