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.
I just run some simple services, such as Audiobookshelf or Wallabag, behind a reverse proxy. After reading the other comments, it does not look like there would be any benefit for my use case.
