Introduction to ICMP Protocol When there is an error in transmitting IP packets – for example, host unreachable, route unreachable, etc., the ICMP protocol will encapsulate the error information and send it back to the host. This gives the host a chance to handle the error, which is why it is said that protocols built … Read more
