Explain how Tracert uses an ICMP packet and the TTL value to map the path to an IP address.
What will be an ideal response?
Tracert sends an ICMP to the IP address with a TTL value of 1. When the first router receives the packet it decrements the TTL to 0, discards the packet, and sends a TTL-expired packet to the sending computer. When the sending computer receives the TTL-expired packet, it notes the address of the first router. Then it sends a second packet with a TTL of 2. This time the packet gets to the second router, is discarded, and the second router sends a TTL-expired packet. When Tracert receives this response, it notes the address of the second router. This continues until the packet reaches the intended IP address.
