How to assign a floating IP to reverse DNS
It is my understanding that a reverse DNS entry should point to the server found in your A records (maybe I am off on this, and if so, feel free to let me know).
Going with that premise, I would think that digitalocean floating IP addresses should update the pointer for the reverse dns to use the floating IP instead of the droplet IP.
However, digitalocean uses the droplet IP and does not allow reassignment to the floating IP. So I have two questions:
Am I off base in my analysis here?
If I am not off base here, what is the appropriate way to get a reverse dns entry for a floating IP?
