Understanding Traceroute
... Traceroute probes the paths to a destination by sending ICMP bursts and incrementing the TTL on those packets. The first burst of three packets has a TTL of one hop, so they never get past the first router. Because these packets have used up their TTL count, the router will return a TE (or Time Exce ...
