Digitalocean hosting - why not use floating IP

[seepanel]

The guidance I am finding on the web suggests using PUBLIC IP instead of FLOATING IP for cpanel installations.
I do not understand this since the whole purpose of floating IPs was to provide some level of permanence to an IP.
I believe DO public IPs are permanent until the server is destroyed but I don't know if that is a guarantee.
Also, what if a server needs to be destroyed and recreated for some reason, the IP is lost.
What is wrong with using a FLOATING IP for a cpanel installation?

Floating IPs are generally meant for High Availability/Failover and don't replace the Public IP address. This is discussed here: Floating IPs :: DigitalOcean Product Documentation

They don't support PTR records which means if you were to configure it as a usable IP you would not be able to send mail with that IP successfully. This is discussed here: Floating IPs :: DigitalOcean Product Documentation

That being said, I don't see anywhere here that recommends you do not use one, the installation instructions on Digital Ocean and our Own Documentation do not note that you cannot use a Floating IP:

How to Install cPanel & WHM on DigitalOcean® | cPanel & WHM Documentation

This document explains how to create a DigitalOcean® Droplet™ running the cPanel & WHM drive image.

Also, we do go over how to manage floating IP's in our own documentation here:

DigitalOcean® Droplet™ Management | cPanel & WHM Documentation

After you create an cPanel & WHM instance on a DigitalOcean® Droplet™, you can manage that instance from within DigitalOcean's portal.

Is it still the case that using a floating IP causes issues for email? If so, it basically means floating IP is useless with cpanel?

@WorkinOnIt - there is not a supported way to use a floating IP address on a cPanel server. The license would change frequently, and the configurations would need to be frequently updated.

@WorkinOnIt - there is not a supported way....

Would something like this work? High Availability on Vultr with Floating IP and BGP " This routing strategy allows a high number of instances with the same configuration to share a single reserved IP as a floating address"

While that isn't something we've tested on our end, I would expect there to be issues with the licensing structure.
