DSL questions for users of 2 or more computers

["Paula" <hotair003@xxxxxxxxxxxxx>]

Hi:
       I am going to get DSL for my 4 networked computers as my ISP can no
longer keep up with the information flow.
       I am curious if anyone is running several computers simultaneously
off 1 DSL address.If so how is the speed and reliability? The DSL company
obviously pushes addresses for each unit ,which I'm willing to do if it
enhances  performance of the DSL service.
        Any response is appreciated.
