Knowing which IP address is active
From a local network, let say there are 10 PCs, and they have the same network host address ( 192.168.1.xxx ).
I would like to find out which IP address under 192.168.1.xxx is active, is it possible? though i still don't know their MAC Address.
1 out of 10 PCs has the software that could/might log all IP address that are used up by those remaining PCs, without installing any software that could communicate to that PC(who have installed the software)
Any reply would be appreciated, :)
