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.

Yes, I have always used a reverse proxy which seems to eliminate the need for multiple IP addresses. It seems like having multiple IP addresses just creates additional cost and complexity, but I have seen many VPS providers offer multiple IP addresses, so I was curious if there was a use case that I was not aware of.

LibreOffice and OnlyOffice are both compatible with MS Office formats. LibreOffice is more popular, but OnlyOffice has better compatibility with MS Office files and the interface is very similar as well.
