Ping scan with nmap

At times you may just need to be able to find out what IP addresses are currently in use on your network.  One quick way to do this is with nmap.

With Zenmap it's just a matter of selecting the "Ping scan" profile and entering a range in the target field, such as 192.168.1.1-254

If you are using nmap from the command line simply type the following, nmap -sP 192.168.1.1-254
