Basically a dummy DMZ is a fake non-existent LAN IP placed in a router's demilitarized zone. Some people have used this technique to send all unwanted traffic from the WAN (internet) side of a router into "nothing". Most people use this to give stealth results when security scans are run. It can also be used to make you stealth while also being pingable.
