Explanation
ICMP (Internet Control Message Protocol) is used for network diagnostics and error messaging. Ping (Echo Request/Reply) - tests end-to-end connectivity Traceroute - uses ICMP time exceeded messages to identify hops Error reporting - returns various error types with different codes However, ICMP does not re-route traffic.
