There are many large hosting companies that do not allow you to delegate reverse DNS entries to your own (PowerDNS) server.

I therefore have to adjust these entries manually with the hoster.

To make this easier for the Virtuel Machine user, I ask that you can set RDNS entries per IPV4/IPV6 in the admin area.
This will then be displayed to customers in the "IP range" of the respective virtual machine.

In this way, I can manually change the entries at the hoster and also show the customer what the current entries are.

As a second step I could imagine (if no PowerDNS is set up) that a customer can change the RDNS in the form that the admin gets the change request emailed and the customer gets a hint that the change will be done manually.
