First of all you need to install NMAP which you can do from this website
http://nmap.org/download.html#macosx
After running the NMAP installer you should restart your shell.
You can do a network ip range scan like this
nmap -sP 192.168.2.0/24
This wil scan the whole ip range of 192.168.2.0 to 192.168.2.255
If you want to specify a range like 192.168.2.1 to 192.168.2.200
nmap -sP 192.168.2.1-200
This will take a while. This is an example of the result you’ll get
Or if you are on a mac you could just download the LanScan application to do this 🙂
You can download LanScan here
thanks bro!! !! !! 😀
