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 also have different SSL settings per virtual host with nginx. No need to use different IPs for that.
I don’t remember the exact details but it didn’t work right. That was arguably a couple years ago on a server distro approaching EOL, may have been long fixed. It involved Android 4.4.
