A traceroute, as the name implies, traces the routes between two IP (Internet Protocol) addresses--for example, a traceroute could be performed to outline the route between your computer's IP address and a website's IP. Traceroutes also include information about the IP address stops along the way, also known as "hops." You won't need to purchase any software to run a traceroute from your computer. Microsoft's Windows operating systems include a free traceroute utility, known as Tracert.

Click on the "Start" button in the taskbar. Click "Run" on Windows XP and previous editions of Windows, or click inside of the search box on Vista or 7 operating systems. Type "cmd" into the Run or Search box, and press the "Enter" key on the keyboard.
Type "tracert 220.127.116.11," and then hit the "Enter" key to trace the route between your computer and your network's modem. You can also substitute for the IP address in the tracert command any other IP to which you'd like to trace the route from your computer. For example, if you wanted to trace the route to the IP address 18.104.22.168, you'd type "tracert 22.214.171.124."
Hit the "Enter" key to get the latency numbers for the time it take the ping to reach the specified IP address and any IP addresses along the way. If you receive the response "Destination net unreachable," then you can deduce that either you've entered an invalid IP address or there is a problem at the specified address.
