WSUS Multiple clients, same name...different IP Addresses

I am deploying WSUS 3.0 SP2 into a lab environment.  I have 6 duplicate networks.  Duplicate up to the IP address that is.  They all use the same names for their systems, by the IP's are different.  For example, their are six differnt machines named "Client 1", but they all have 6 DIFFERENT IP addresses.  In my WSUS console, I can get the machines to show up, but it looks like the machines with the same name are being seen as the same device despite the different IP addresses.  

Is there a work around for this?
