Hello, @zedisblue

The Reverse DNS is configured automatically from our end based on the droplet’s hostname.

To rename your droplet via the control panel, do the following:

Login to the Digital Ocean Control Panel

Go to Droplets --> Click the droplet you want to rename

Then, on the droplet detail window, click on the name of your droplet (you wouldn’t know you could)

Go to the Settings Tab --> Change the name in the entry field and click the check mark

Make sure you also edit your droplet’s hostname internally as well. Update /etc/hostname and /etc/hosts and reboot.

The PTR should be automatically adjusted in few hours due to DNS cache. If this is still not working after several hours, you can contact our support team as well.

What’ll recommend is using a generic name for the hostname so both domains can use it.

Regards,
KDSys
