You need to implement scanning over the network for obtaining live ip's on your network. For doing this you need to take a ip range and try to ping the ip in a loop. The range can be obtained from your own ip. For instance if your ip is 10.0.0.2 then probably all the ip's will lie in 10.0.0.0 to 10.0.0.255. In case you want to check for other ip's you need to ask for range.
