Let’s take a look at the basics of using Wireshark to capture and analyze traffic. It can decode different protocols that it sees, so you could, for instance, reconstruct the audio of Voice over IP (VoIP) phone calls.

Wireshark can be used to capture Ethernet, wireless, Bluetooth, and many other kinds of traffic. Wireshark is a graphical network protocol analyzer that lets us take a deep dive into the individual packets moving around the network.
