Explanation:
Detailed explanation-1: -If the resulting TTL is 0, the packet is discarded and an ICMP time exceeded in transit message is sent to the datagram’s source address.
Detailed explanation-2: -ICMP (Internet Control Message Protocol) is an error-reporting protocol that network devices such as routers use to generate error messages to the source IP address when network problems prevent delivery of IP packets.
Detailed explanation-3: -Ping uses two ICMP codes: 8 (echo request) and 0 (echo reply). When you issue the Ping command at the prompt, the Ping program sends out an ICMP packet containing the code 8 in the Type field.
