Once a droplet is up, we get a reverse DNS entry associated with the IP. That's great :-)
Having DNS management on DigitalOcean is also great.
But -- you could take that one step further. Having delegated the ".do.XYZ.QW" zone to DigitalOcean, when starting up a server I use "name.do.XYZ.QW" as the hostname.
Yet I have to create the A record manually. Not a big deal, but it could be easier :-)
Since the zone is already managed by DO, how about creating a matching A record automatically?
