How to Change Default Size of Ping Echo Request On Your Computer(ping -l)

We all know by default the size of ping ICMP echo request packet is 32 byte.

If you set any value not in the range of 0-65500, you will get error with warning bad value for -l, value range is from 0 to 65500. If you are facing issues with MTU value of ICMP packets send from your computer, changing their size may help you. The format to change the default ping echo request packet size is given below.
