When creating a droplet, you have to fill in a “Hostname”. I’m a newbie and curious what it’s used for and what it is. Is it just what separates each droplet from each other or is it much more then that? Isn’t the hostname supposed to be “Localhost”? I’m really confused!

A droplet/server’s hostname is basically its name. You can name it anything you want, such as your domain name or the name of a Greek god ;) <br> <br>Your IP’s PTR/rDNS record is set to your droplet’s hostname so if you’re going to run a mailserver you have to set it to your FQDN.
For me, the public IP was the hostname. I used it to find the “host” “hash” with: ssh-keygen -H -F <my.ip.was.here>
