A small page about ping.

Ping is a reachability check. A host answers an echo request, and you read the round-trip time. That is all this page is about.

ping -c 4 example.com
64 bytes from example.com: icmp_seq=1 ttl=54 time=18.2 ms

What the numbers mean

Time is latency. TTL is remaining hops. Packet loss means the path dropped replies, not that a website is “down” by itself.
