To use ICMP type 8 we write :
>ping IP@.
I was wondering what commands would allow me to use other types of ICMP like type 13?
(You mention "CMD", so I'm going to answer this under the assumption that you are talking about DOS/Windows.)
The ping
command in Windows only sends Type 8 (Echo Request). If you want to send other types, you'll need a third-party utility.
