In this example we will use genlist along with nmap.

First we will generate list of live hosts and save it to a file called “list” with this command:
genlist -s 216.109.112.\* > listNow we will use Nmap to scan that list with this command:
nmap -v -iL list

(To know more about nmap check out my previous comprehensive debunk of nmap options over here:
