What are the benefits of a server having multiple public IP addresses? (lemdro.id)

My VPS provider is running a promotion where I can get up to 5 additional public IPv4 addresses for a one-time cost of $25 each. I have always only used a single public IP address per VPS. Would there be any advantage of having additional public IP addresses?

I know some people do not consider a VPS self-hosting, but this is the most relevant community I could think of and the question is also applicable for homelabs as well.

Depending on the service, you totally can, provided they include some way to recognize them. For example, the first few bytes of SSH are unique, so I made a simple TCP server that would forward traffic to an HTTP(S) server or SSH server depending on those bytes.
