Traceroute
Traceroute is the program that shows you the route over the network
between two systems, listing all the intermediate routers a connection
must pass through to get to its destination. It can help you determine
why your connections to a given server might be poor, and can often help
you figure out where exactly the problem is. It also shows you how
systems are connected to each other, letting you see how your ISP
connects to the Internet as well as how the target system is connected.
