accessing subdomains via ip

using wpmu

I moved my blogging service to another server... in haste maybe...
thought I copied enough of what I needed, turns out I left a thing or two...
I am on a new server now and trying to figure out how I can retrieve some things from the old server.
I had subdomains setup up with a wildcard * as customerblog.mydomainname.com

any chance someone knows how I can access the subdomains on the old server can't even seem to get into the admin using the ip/login.php

any help would be highly appreciated.

Thanks.
