The machine that is presenting you with this page, does indeed serve several web sites. You would have to provide the correct domain name in order to get to them. It would be hard to guess otherwise which of them you are looking for.
There are also a few (sub)domains that will lead you to this particular page, since they are not used for a web site, but for other purposes (e-mail for instance).
No. Don't be silly. I'm just a random machine somewhere in an anonymous data centre. It would feel inappropriate.
