Enable this option to allow users to set a custom format for reverse zones. Once enabled, custom reverse zone name formats can be configured either at the IP Block or IP Network level.
To enable custom reverse zone formats:
- Select the Settings tab in the sidebar.
- Under DNS settings, select Custom reverse zone.
-
Select the Allow custom reverse zone formats check box
to allow users to set custom format for reverse zones.
Note:
- If you set the reverse zone name format at the IP block level, it will be inherited to the child networks. If you want to override the reverse zone name format set at the higher IP block level, set a reverse zone name format at each child network level.
- Class-C classless reverse zone format applies only at levels smaller than /24 networks. The format should be able to uniquely identify the network.
- The default reverse zone name format is: [start-ip]-[net-mask].[net].in-addr.arpa.
- Supported formats include:
- [start-ip]-[net-mask].[net].in-addr.arpa
- [start-ip]-[end-ip].[net].in-addr.arpa
- [start-ip]/[net-mask].[net].in-addr.arpa
- [start-ip]/[end-ip].[net].in-addr.arpa
- User-specific custom format. User-specific custom format only appears and can only be set at the subclass C classless network level.
- A deployment role must be assigned to a particular network or block otherwise the reverse zone name format won't take effect.
- In the Change control section, add comments if required.
- Select Update custom reverse zone settings.
