A forward DNS server group is a collection of one or more external DNS servers. Grouping a set of external DNS servers together to a forward DNS server group reduces the configuration efforts. You can assign a single forward DNS server group as default forwarders for a forward zone instead of specifying multiple DNS servers individually.

Note the following while adding a forward DNS server group:

  • You cannot add a forward DNS server group if a group with the same name already exists.

  • You cannot delete a forward DNS server group if it is assigned to a zone.

You can associate these with forward-mapping and reverse-mapping authoritative zones.

To create a forward DNS server group, complete the following:

  1. From the Infoblox Portal, click Configure > Networking > DNS Server Groups > Create > Forward DNS Server Group.
  2. On the Create Forward DNS Server Group page, specify the following:
    • Name: Type a name that provides a meaningful reference for this set of servers.
    • Description: Optionally, enter additional information about the forward DNS Server Group.
    • DNS Servers: Select the DNS Servers from the list. 
    • FORWARDERS: Click Add and select one of the following options for every server that you are adding to the DNS server group.
      • Forward to Address: Enter an external IP address to which you want to forward the queries.
      • Forward to NIOS-X Server: Select a NIOS-X Server address from the drop-down list. The queries against the zone are forwarded to this NIOS-X Server.
      • Forward to DNS Server Group: Select a DNS Server Group from the drop-down list. The servers in the DNS Server Group serves the zone and forward queries.  

    • Tags: Click Add to associate keys with the reverse-mapping zone and specify the following details:

      • KEY: Enter a meaningful name for the key, such as a location or a department. 

      • VALUE: Enter a value for the key.  

    To remove a tag, select the respective check box and click Remove to delete the associated tag. For information about tags, see Managing Tags.

  3. Click Save & Close to save.
