[Phpwm] virtual hosts in apache

[sukh virdee]

Hi,
I've set up a virtual host on my dedicated server with a dummy domain name. 
I only have one IP address for the server.

How can I access webpages that i have created for the virtual host through 
my browser. I've heard that when using windows and IE you can make an 
addition to  the host file and then you can access the dummy site through 
the IP address...?

Any ideas,
Sukh
