So I have ubuntu 14.04 droplets. The FQDN is set in the hosts file. I see in some threads that if I rename my droplets to I’m assuming their FQDN that the reverse dns lookups will be created. Is this correct? If so, how do I rename my droplets?

One way I found to rename a droplet is to take a snapshot and then create a new droplet with a different name based on the snapshot:
- shutdown droplet named A (and keep it shutdown)
- from DO control panel, take snapshot of droplet A
- from DO control panel, create a new droplet named B based on snapshot of droplet A
- configure droplet B DNS entries and unconfigure droplet A (take notes before you do)
- boot droplet B and wait N hours to test propagated DNS entries
- if droplet B works, then delete droplet A
