I would like to host all my clients websites . Lets take for example i have 3 websites.

www.one.com
www.two.com
www.three.com

I would like to host all three using just one webhost provider. So lets say i sign up for a package that provides me with 300mb of space etc. How do i check if they would allow different urls in the same package. Most of the times i see subdomains but i dont need those.

Please help....
