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.
The main thing is log separation
It’s a lot easier to figure out why your service is broken if it’s the only service on the IP versus there being 10 services on the same IP all dumping into the same log. Lets me grep a lot easier
