Testing vhosts on ispconfig3 without a domain name

Hi,

I'm working with ISPConfig3 on a Debian Lenny server. I want to setup a virtual host and test it before I transfer the domain yet there is no way to do this directly through the ip address. All the vhosts are setup through symlinks that I can access with the shell but not through the web (ie http://123.123.123.123/domain.com/web is similiar to where the link points to that I can't open). Is there a way to test a domain name before it has been resolved?

This is an actual server on an outside network and not my personal machine.

Thanks

Thanks. I didn't see that one while searching.
