Configuring DNS Config Profiles

A Global DNS Configuration contains all the settings required to run a NIOS-X Server as a DNS server.  A DNS config profile is configured and applied locally to the NIOS-X Server. All configuration settings are inherited from the Global DNS Configuration into the DNS config profile by default. If there are no changes made to the DNS config profile, it would be an exact copy of the Global DNS Configuration. For more information, see Global DNS Configuration. 

However, in some instances, you may need to configure settings that are different from the Global DNS Configuration. In such instances, you can override the values inherited into the DNS config profile. There are only two configurations available for inheritance in the DNS config profile: 

• Inherit - this is the default setting. The values for the particular setting exactly matches the value provided in the Global DNS Configuration. 
• Override - you can toggle the configuration to Override and provide alternate values.  Use this setting when you want to provide a value for a setting that is different from the one specified in Global DNS Configuration

You cannot delete a DHCP config profile if it is in use by a NIOS-X Server. A DHCP config profile may be assigned to multiple NIOS-X Servers.

The DNS config profile is applied locally to a NIOS-X Server. The DNS config profile contains all the settings required for the particular NIOS-X Server. For example, an organization creates a Global DNS Configuration at the head office. The branch office can deploy a DNS server (NIOS-X Server) and inherit values from the Global DNS Configuration. For settings unique to the particular branch office, the organization creates a DNS config profile to override settings in the Global DNS Configuration and apply it to the NIOS-X Server. The following diagram shows the stage at which the DNS config profile is configured:

For example, an organization's secondary DNS server (NIOS-X Server) located in the head office may need to accept zone transfer requests from the cloud. However, the second DNS server (NIOS-X Server) at the branch office may need to be configured to accept zone transfer requests from an external primary server. The DNS config profile and the Global DNS properties are applied together as shown in the diagram:

To view the list of DNS config profiles, complete the following:

1. From the Infoblox Portal, click Manage > DNS > DNS Config Profiles.
2. Universal DDI displays the following information for a DNS server:

• NAME: The name of the DNS server is shown in the table.
• DESCRIPTION: Information about the DNS server is shown in the table.
• NIOS-X Server ASSIGNED: Displays the NIOS-X Servers that are associated with the DNS server in the Info panel.

You can also perform the following in this tab:

• Click the menu button, , and select the columns to be shown.

• Click the menu button, , and then Edit, or select the check box for the respective record and click the Edit button to modify a DNS server.

• Select a DNS server to view the details on the right-hand panel. You can view details like name, description, type, tags, queries, recursion, DNSSEC, server details, and EDNS Client Subnet Configuration details that are associated with it. If you do not want to view the details in the right-hand panel, click the information button, .

• Enter the value that you want to search in the Search text box. The application displays the list of records matching the keyword in the text box.

• Click the filter button, , to filter the objects by name, description, and tags. To save a filter after selecting the required parameters, click the save button, , specify a name for the filter, and click Save & Close. To reload a previously saved filter, click the start button, , and select the required filter. 
  

• Click  the menu button, , and then Move to Recycle Bin to move the object to the recycle bin. You can restore the object later or delete it permanently as required. For more information, see Recycle Bin.
