Key Concepts

ICMP

ICMP (Internet Control Message Protocol) is a network layer protocol used by network devices to diagnose network communication issues and to report errors in IP operations, such as message delivery failures.

Echo Reply

The ICMP message type 0, known as Echo Reply, is used as a response to an Echo Request message (ICMP type 8). It serves primarily to verify the reachability of a host on a network and to measure round-trip time in network diagnostics, such as with the ping utility.
