web-hosting

Hi, I am a Computer Science guy who understands networking very well. But when it comes to Web hosting companies I am clue less. I want to know how do web hosting companies give so many public IPs to so many users and each of them has root login also. How this is technically done that is what I am interested to know. I do not know how you people configure it.

In my case if I have to do I will buy a public IP from some one and connect my server to it and at max give some people SSH access to it.In case of Web hosting companies how is it done.
