Probably a rather dumb question, but not the point. I would like to know how to assign several or more ip addresses to one server?

Answer 1

normally assigned. This is implemented in all operating systems.
In addition, there are options:
1. the computer has 1 network adapter with several addresses
2. several network adapters, each can have several addresses.
