ICMP (Internet Control Message Protocol) is used for error reporting and determining whether a packet successfully reaches its destination. It sends messages to routers or hosts to check the status of the network and provides feedback on issues that are preventing successful packet delivery. UDP (User Datagram Protocol) does not guarantee delivery of packets, TCP (Transmission Control Protocol) ensures reliable packet delivery but does not specifically report errors, and IP (Internet Protocol) is responsible for routing and addressing packets but does not confirm delivery.
