Traceroute operates by sending a sequence of Internet Control Message
Protocol (ICMP) echo request packets. The time-to-live (TTL) value, is used
in determining the intermediate routers through which the packet flows
toward the destination address. Routers decrement a packet’s TTL value and
discard packets whose TTL equals 0. On discarding a packet, the router
returns an ICMP time exceeded message to the source.
