How can Nmap scan multiple IP addresses at once?

You can use Nmap to scan multiple IP addresses at once by specifying the IPs directly in the command or by using a file that contains the IP addresses. Here are two methods:

Method 1: Directly in the Command

You can list multiple IP addresses separated by spaces:

nmap 192.168.1.1 192.168.1.2 192.168.1.3

Method 2: Using a File

1. Create a text file (e.g., targets.txt) with the IP addresses, one per line:

   echo "192.168.1.1" > targets.txt
   echo "192.168.1.2" >> targets.txt
   echo "192.168.1.3" >> targets.txt

2. Use the -iL option to read from the file:

   nmap -iL targets.txt

Both methods will allow you to scan multiple IP addresses in a single Nmap command.
