Background
Route tracing computer software is a utility that lists the networks data has to traverse from the user's originating end device to a distant destination network.
This network tool is typically executed at the command line as:
tracert
(Microsoft Windows systems)
or
traceroute
(Unix and similar systems)
Route tracing utilities allow a user to determine the path or routes as well as the delay across an IP network. Several tools exist to perform this function.
The traceroute (or tracert) tool is often used for network troubleshooting. By showing a list of routers traversed, it allows the user to identify the path taken to reach a particular destination on the network or across internetworks. Each router represents a point where one network connects to another network and through which the data packet was forwarded. The number of routers is known as the number of "hops" the data traveled from source to destination.
The displayed list can help identify data flow problems when trying to access a service such as a website. It can also be useful when performing tasks such as downloading data. If there are multiple websites (mirrors) available for the same data file, one can trace each mirror to get a good idea of which mirror would be the fastest to use.
Two trace routes between the same source and destination conducted some time apart may produce different results. This is due to the "meshed" nature of the interconnected networks that comprise the Internet and the Internet Protocols ability to select different pathways over which to send packets.
Command-line-based route tracing tools are usually embedded with the operating system of the end device.
Other tools, such as VisualRoute™, are proprietary programs that provide extra information. VisualRoute uses available online information to graphically display the route.
This lab assumes the installation of VisualRoute. If the computer you are using does not have VisualRoute installed, you can download the program using the following link:

If you have any trouble downloading or installing VisualRoute, ask your instructor for assistance. Ensure that you download the Lite Edition.
