ICMP

ICMP (Internet Control Message Protocol) carries diagnostic and error messages between devices on a network, rather than application data. Routers and hosts use it to report problems like an unreachable destination or an expired packet, and tools like ping and traceroute rely on it directly. It works at the network layer, alongside IP, but it doesn't transport regular traffic.
