Reading and understanding the traceroute information block

Traceroute Information Block Screen

The Traceroute Block is a computer network diagnostic tool for displaying the route and measuring packets' transit delays across an Internet Protocol (IP) network.  

The route's history is recorded as the round-trip times (RTT) of the packets received from each successive host (remote node) in the route or path; the sum of each hop's mean times is a measure of the total time spent to establish the connection. Traceroute proceeds unless all (three) sent packets are lost more than twice, then the connection is lost, and the route cannot be evaluated.

Important Note: Not all hops in a traceroute will be configured to respond to ICMP. So, the result may show a 100% loss on such hops. For security reasons, it is not uncommon for major ISP routers to be configured in this manner.
