What is the meaning of UDP ping?

[nifflin]

Isn't ICMP ping not enough? In what scenario does the UDP ping works better than ICMP ping?

I think the readme partially addresses this.

This package implements ICMP ping using both raw socket and UDP. If your program uses this package in raw socket mode, it needs to be run as a root user.

I wanted to be able to run my program without root access, so I used UDP. I can't advise you on anything more detailed than that, but hopefully this helps.
