ICMP messages provide the system with a way to notify the source host if the remote host is not receiving the transmitted packets. It simply exists as a feedback system, a resource to identify problems with lost packets and broken data routing. Destination Unreachable messages are generated for several reasons, including unable to reach a network, a host, a port, or a protocol.
A router sends these Destination Unreachable messages back to the host, which then usually sends it to the application that generated the original packet. The error messages let the application know to try again and, if needed, the host application can generate an error message to the user of the application, notifying them of network connectivity problems. Other important messages include the Redirect message, which a gateway uses to let the host know to send traffic to a different router.
