multiple domains

Hi all! I have web hosting which I pay for but I have found that the IP number is shared by other domain names. How is this done? I don’t really understand this because when I FTP to my “/www” directory I only see my own files. If I try to access the site using the IP number I just come up against a place holder. What I don’t really understand is this: when I go to the site I must be redirected to a sub-directory of the IP but this is not shown by the domain name which still indicates that I am in the top level directory. In other words there is no redirection being carried out but I end up in the sub-directory. How is it possible?

Just for your information the domain name is:

[URL=http://www.moralet.com]www.moralet.com[/URL]

and the IP number for it given out by the DNS is:

[URL=http://83.244.130.93]83.244.130.93[/URL]

Thanks in advance for any enlightening information. ?
