Note: many of these websites will have extensions when viewing them in a browser to change the
language based on the country that the website is being viewed. The websites listed in the table on the
previous page is all that is needed for the commands used in the steps below. If you want to view these
websites in a browser, please google them first to ensure that the website displays properly using a
language that is not the University's native language.
Advice: If possible, use an actual windows computer (personal or RMU Lab) to complete this assignment.
If neither of these options are possible, using Appstream (Academic option) through
https://view.rmu.edu is acceptable, but the command prompt command output will differ due to the
computers being virtual. 1. In a Command Prompt window, run tracert on a website whose servers are located in a different
Country from your location. Your website to use for this assignment can be found in the table on
the previous page. What command did you use? Take a screenshot of the results for your
submission.
2. Examine the output and find the point in the route when messages started jumping across the
ocean (or otherwise out of the country). By what percentage does the RTT increase after the
jump compared with before it? You can see an example here.

To calculate the percentage for this jump, select a time from just after the jump (114, for
example) and divide it by a time from just before the jump (such as 16), then multiply by 100
percent: 114/16 X 100 = 713%. In this case, the sample data yields a 713 percent increase. It
takes 7 times as long for a message to go round-trip from the United States to Germany (the
location of the first non-US router), as it does for a message to travel round trip between two
servers that are both located within the United States. 3. Choose another website whose servers may be in a different country from this one. Select one
version of Amazon's website from the list below - but choose a different country from the
university website you just worked with.

How many hops did it take until the route crossed an ocean (or border)? What other anomalies
do you notice about this global route? Take a screenshot of the results for your submission.
4. Scott Base in Antarctica runs several webcams from various research locations. Run a trace to
the Scott Base website at antarcticanz.govt.nz. Take a screenshot of the results for your
submission. What's the closest router to Scott Base's web server that your trace reached? If
you can't tell from the command output where the last response came from, go to
iplocation.net in your browser. Enter the final hop's IP address to determine the router's
location.
Submission for this Assignment:
You may enter your submission directly into Blackboard, or into a word/google doc and attach it. Your
name, and the following will need to be present in your submission for all points to be awarded:
1. Provide a screenshot containing your tracert command output your assigned University.
2. What was the change in RTT you noted in step 2 of this assignment activity? This should be a
percentage specific to your university assignment and the detail present in your screenshot from
step 1.
3. Provide a screenshot containing your tracert command output for the Amazon website you
chose. How many hops did you notice it took until the route crossed an ocean (or border)?
4. Provide a screenshot containing your tracert command output for the Scott Base web server.
Note the closest router to the web server that your trace reached, where did you find it was
located? Also, provide a screenshot from your query using iplocation.net.
