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.
You can run a service on the same port with less processing overhead than a reverse proxy. Additionally it provides you some benefit in domain separation. For $25 I’d pick up one or two, couldn’t hurt to have in the pocket and there are only so many of them afterall.
