Part of this week's lab, you need to install Wireshark, Wireshark provides a means to see what packets actually look like. To become familiar with Wireshark and how it works, please read the short tutorial on howtogeek.com. To try out Wireshark, here are a set of sample capture files you can take a look at.

Note: The tutorial mentions a "quick warning" about using Wireshark at work. It's perfectly fine to use Wireshark to look at packet traces, but you should NOT use it to capture packets on networks that you don't own/manage. You don't have to worry about this issue in the lab, because you can't even turn on the capture feature without being an administrator.

We will also explore (and modify) websites using the Google Chrome DevTools. You need to become familiar with the tools.
