Traceroute is a network diagnostic utility used for displaying the path taken by a packet to it’s destination. It uses the ICMP protocol to help traverse the path. Each IP packet has an 8 bit TTL field that gets decremented by every router on the path, to prevent the packet from indefinitely circulating the internet (or network). When the TTL value reaches zero an ICMP error ‘Time To Live Exceeded’ is sent back to the sender. We can use this fact to our advantage by discovering all the hops between the source and the destination.
