Often, we will want to scan a list of IP addresses and not an entire subnet. We can use any text editor and create a list of IP addresses, and then feed this list to Nmap. Here, I am using Leafpad, which is built into Kali (any text editor will work), to put together a list of IP addresses I want to scan:

Then I can use this list of IP address in Nmap rather than having to retype these IP addresses each time I scan. Type pwd to see the working directory. Then we can create our scanlist file there with a text editor. We will be adding 192.168.10.2, 192.168.10.50, 192.168.10.70, 192.168.10.100, and 192.168.10.200. Type nmap -iL scanlist.txt:

As you can see, Nmap scanned all five IP addresses that I listed in my text document, but only found two IP addresses among them.
