Master Server Group Administration

A master server group allows you to group and manage master name servers from a single location instead of from each secondary zone group or secondary zone.

Key information:

• The name assigned to a master server group or a master name server is simply a label to allow easy identification of that group or name server.
• A master name server can belong to multiple master server groups. If you have previously created a master name server in another master server group, you may simply select it when defining the membership of a new master server group.
• TSIG administration can be performed when adding or modifying a secondary zone group. Changes to a TSIG key are immediately reflected across all secondary zone groups. This allows you to make bulk changes to TSIG keys that affect many secondary zone groups and associated secondary zones.
• Once a master server group has been associated with a secondary zone group, its name servers will be queried every 120 seconds for each zone identified in that secondary zone group. For this reason, we recommend that a master server group should only consist of name servers that are authoritative for the same set of zones. Likewise, a secondary zone group should be limited to those zones.
