Updating name servers
To modify the name servers for an active domain name, please use the Registration form and check box 8b, indicating the new server names.
You must notify DNS-LU of at least two name servers with the correct configuration for the name in question. This information is available from your internet service provider who is also responsible for configuring machines.
If you require further information to help you complete the form, please read the section How to complete the registration form. The form is also used for declaring any technical domain name modifications.
The name servers indicated by you will be tested. DNS-LU only activates a domain name on the new machines if the two name servers are operational when the new server information is provided.
To check whether your servers are configured correctly, you can use the Name server test tool, which provides a test identical to those used by DNS-LU. Only domain names with servers approved by these tests will be activated by DNS-LU. Technical information on how the test works is also provided.
A Change of provider is, in principle, only the replacement of server names and the technical contact, who must be confirmed by the administrative contact.
