nmap Host Discovery

nmap can useful command line tool to check what hosts are alive on a particular network. I often use the the nmap with the -sn switch. This option tells Nmap not to do a port scan after host discovery, and only print out the available hosts that responded to the host discovery probes. This is often known as a “ping scan”.

nmap -sn 192.X.X.X/24

A full list of switches can be found on the nmap website here.
