You can use Traceroute to trace the path to a network host or device.
The Traceroute tool shows you the network path used to reach a specified TCP/IP address. (Note that Traceroute will not show the return path, only the path used to reach the address.)
The Traceroute tool also displays response times (in milliseconds), which identify the amount of time it takes the packet to travel the route. Response times will vary depending on network load.
In tracing the path to a remote host, you can also specify that the traceroute go through another host or hosts. This is known as loose source routing. This is useful when there are multiple paths between the hosts and you want the traceroute to go through a specific interface or router. Note that not all routers allow loose source routing.
The Traceroute tool is useful for finding potential trouble spots on large and complex networks that are connected together with routers.
