With the Reverse DNS Management Plugin, which we deliver for free with the module, you can add reverse DNS servers and admins and customers can manage the reverse DNS record of IPs. The plugin is fully AJAX driven.
We decided to add PowerDNS as the first provider because PowerDNS is very common and is also used by SolusVM and Virtualizor. So the existing name servers can be added to the module. However, the Reverse DNS Plugin is flexible and expandable. Anyone with knowledge of PHP can add their own providers, so you can expand the number of supported providers yourself. For example, it is possible to integrate the data center API for RDNS management.
For maximum flexibility, multiple RDNS servers can be added and different subnets can be assigned to each RDNS server.
