Online traceroute network utility

The traceroute mini-bot reveals the network path between and a given ip or hostname. Traceroute is considered as the swiss army knife amongst the network guys! It is also used to measure the latency between hops (nodes)

In computing, traceroute is a computer network diagnostic tool for displaying the route (path) and measuring transit delays of packets across an Internet Protocol (IP) network. The history of the route is recorded as the round-trip times of the packets received from each successive host (remote node) in the route (path); the sum of the mean times in each hop indicates 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.
