TCP/IP does not support a way to query a network to find host addresses.
Iterating through IP addresses, pinging to find active addresses is usually seen by network administrators as a threat, and is frowned upon.
There are protocols built on top of TCP/IP,Jini, for example , which do make it possible to discover network resources.
