Deploying to IP using reverse lookup

During our MDT image process we kick off a deployment to the computers IP as part of the task sequence. This avoided DNS problems as for laptops we have different subnets for wireless and lan, and often deploying to hostname would send the deployment to the laptops Wifi IP address which wasn't in use during the MDT process. The IP address method did work whilst we didn't have DNS reverse lookup configured, but I set that up last week and now PDQ does a reverse lookup on the IP address to get the hostname, then resolves the hostname to an ip address via DNS. So basically we then have the same problem as before where there is a 50/50 chance that DNS gives out the Wifi subnet address. I set this up to avoid the need to delete DNS records every time you reimage a computer. Is there a way of just deploying ip address and not doing any reserve lookup?
