In primary zones, it is not possible to delete NS records for Hetzner name servers (see this FAQ). However, you can add additional NS records for external name servers that should be used together with Hetzner name servers. To add new NS records, follow this getting started. You can edit existing NS records via the Hetzner Console as explained below.
To manage the name servers on your Hetzner Console, please open your project and do the following:
-
Go to DNS on the left menu bar
-
Select the respective zone
-
Scroll down to the "Record overview" and expand the list of NS records
Select the three dots to the right of the name server and select "Edit record". Note that you can only edit the value of NS records for external name servers. With NS records for Hetzner name servers, you can only edit the comment.
Update all name servers as needed and save your changes.
