From the Update DNS option inheritance settings window, you can control whether DNS options are inherited by child zones within a configuration. When DNS option inheritance is disabled, DNS options that have been configured on a zone aren't inherited by the child zone. In the reverse space, DNS options that have been configured on a block aren't inherited by the child block or network when DNS option inheritance is disabled.
Limitations:
- Disabling DNS option inheritance only affects options attached to a zone or block and the inheritance of those options by child zones, blocks, or networks.
- You can't disable the inheritance of DNS options that are attached to a configuration, view, or server. These DNS options will continue to be inherited by all zones, blocks, or networks found under the object.
To disable DNS option inheritance:
- Select the Global tab in the sidebar, then select Configurations.
- Select the name of a configuration that you want to edit in the Configurations table.
- Click the down arrow (configuration name menu) next to the configuration name, and select DNS option inheritance.
- Under General, select the Disable DNS option inheritance checkbox.
- In the Change control section, add comments if required.
- Select Update settings.
After changing the DNS option inheritance on any configuration, the
subsequent deployment to all DNS/DHCP Servers will be a full DNS
deployment.
