I’m trying to figure out just what “floating IPs” are good for.
Are Droplets given DHCP addresses on creation, or addresses that aren’t accessible outside other Droplets?
ie: Do I really need to assign a floating IP to, for example, a mailserver?

Hello,
In general, the moment you create a Droplet, you will be assigned an Static IPv4 address automatically. Similarly, when you destroy the Droplet, the IP address will be disassociated and will join the IP pool table. There is no way you can have one more Static IP address to the Droplet on our platform. Really sorry for the inconvenience!
However, you can use the provision of Floating IP on our platform. This allows you to assign one more IPv4 address and can also be moved between Droplets in same account. Refer to below links, which provides some insights on Floating IP:

You can also start using IPv6, request you to refer to below links:
