A name server (NS) group is a collection of one or more DNS servers. Grouping a commonly used set of DNS servers together simplifies zone creation by enabling you to specify a single NS group instead of specifying multiple name servers individually.
You can configure the following types of name server groups:
...
- From the Data Management tab -> DNS tab -> Zones tab -> zone checkbox, and then click the Edit icon.
- In the Authoritative Zone editor, click Name Servers.
Select Use this name server group, and then select the authoritative NS group from the drop-down list.
Note title Note If you apply a name server group to at least one zone or specify it as the default group, you cannot rename or remove it. To rename or remove a group, you must first disassociate it from all zones and unassign it as the default group.
Using Delegation Name Server Groups
A delegation name server group is a collection of external name servers for delegated zones. Adding a set of external name servers to a single delegation name server group can significantly reduce configuration efforts. While configuring delegated zones, you can specify a single delegation NS group instead of configuring multiple name servers individually. After you create a delegation NS group, you can then assign it to serve only delegated zones. When you assign a delegation NS group to a delegated zone, Grid Manager automatically generates an NS record, a glue A or AAAA record, and a PTR record for each name server available in the delegation NS group. But if the zone is disabled, Grid Manager does not generate these records.
Note the following while adding a delegation NS group:
