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.
Yup, I was reverse proxying early in my career, and I even built my own once for fun (I “hid” an SSH server on my HTTP server by looking at the first few bytes and proxying appropriately).
