ICMP Latency Check

A simple Bash script that pings multiple targets and sorts them by average latency. Useful for choosing the nearest datacenter based on latency.

The IP addresses in the examples directory were taken from public sources (Shodan.io, RIPE NCC, web search).

Usage

Command	Effect
./ping.sh	3 pings, use default.txt
./ping.sh 10	10 pings, use default.txt
./ping.sh examples/upcloud.txt	3 pings, use uplcoud.txt
./ping.sh 10 examples/hetzner.txt	10 pings, use hetzner.txt
