Yeah the DHCP list only shows the IP of clients whom the DCHP server handed out an IP to. I heard there is a way via the command line to see all of the computers on the network.
Thx this is very ridicule, This means that if I set ip address ASG -like the CISCO Core Switch, don't ping the ip address? and ASG work as long as sense the conflict ?!! However, Thank you for your answer my dude.
you can add some static mappings(you need the mac-address though), in the DHCP-server(network services>dhcp>static mappings), to avoid duplicate IP's on your network.
