Use a traceroute tool and explain the difference between IP addresses and URLs
Remember our convention.
commandsargumentvalue
Using a traceroute tool, trace the route the packets take from your computer (whether you start with your client or with a server) to any domain name you are interested in.
Please run a traceroute on its domain name (in this case, you will need to include the full www.name.top_level_domain), then copy and paste a screenshot of your results into a file. We are interested in how many hops it takes to get from your location to this site. If the trace can tell exactly where this site is, I will see it in your screenshot. If the trace times out prior to reaching the site, I will see how many hops it took prior to timing out.
If you don't have any domain names you are interested in, here are a few you can use.
Use your ALT+PrtSc tool to capture a screenshot of the data you want, then save the captured image into a file of some sort. It could be a .docx file, a .rtf file, a .pptx file; it just needs to be a file that can hold the image. If you can save the image as a .jpg, .png, or any other image format, that would suffice as well. It just needs to be able to be downloaded.
After you have saved the file on your client, FTP it into your password-protected directory, from where it can be retrieved.
The structure takes advantage of how operating systems want to index things.
LastName.FirstName(s).YYYYMMDD.TaskNN.descriptor.file extension
An example might be
johnson.pat.20190128.task01.06.traceroute.pdf
Send me the file name.
Whether or not the traceroute times out prior to arriving at this site, I would like you to do answer one question as well.
You can add this to your email note.
Can you describe the difference between the IP address and the URL? Why does the trace go to an IP address and not to a URL?
You are to do the traceroute, but you can also see a web based traceroute tool do the same thing.
