A PTR record is created on managed DNS Servers by default for every host record, if the Reverse Record check box is selected, and you have set the necessary deployment roles. However, there may be situations when you need a DNS server to be authoritative for certain reverse zones, but not authoritative for the corresponding forward zones.
To accomplish this, you still need to create the forward zones and host records to ensure that the PTR records are created. You then assign the deployment role of None to the forward zone. This ensures that the reverse zones are deployed to the managed DNS Servers while the forward zones aren't.
To deploy the reverse zone only:
- Create the necessary DNS forward zone.
- Create the necessary DNS host records within the zone ensuring that the Reverse Records check box is selected.
- Assign the deployment role of None at the forward zone level.
- Assign the deployment roles at the IP block or network object.
