    How Does Traceroute Work

    Enrique

      My understading has always been that it sends out 3 udp packets with a TTL of 1, that returned, it sends out another set with a TTL of 2 and so on until it reaches the intended destination. Is this the Unix version? Are there other versions of Traceroute that use ICMP instead of UDP packets? Can someone who has a master grasp of the matter explain? Thanks.
