This article will begin with the basics, such as what Wireshark is and why we use it. I’ve also reviewed its basic applications and demonstrated an overview of the Wireshark interface. Finally, we’ll see how to utilise Wireshark with its basic filters, colour coding, and real-time network traffic capture.
What is Wireshark?
Wireshark is a network protocol analyzer that captures packets from the network and is commonly referred to as a packet sniffer. Your network could be your house, office, or agency, for example. Wireshark, like other packet sniffing programmes, can perform a variety of tasks. Wireshark’s most useful features are packet capture, filtering, analysing, and visualisation.

Overview of Wireshark Interface
When you initially start Wireshark, it will open a window that lists all of the possible interfaces on your system, so you must first decide which one you wish to capture.
In the screenshot above, you can see that I’ve selected the WiFi interface.
After selecting the interface, you’ll be sent to Wireshark’s main window, where we can see a variety of options.
On the options bar there are 11 options such as a file, edit, view, go, capture, analyze, statistics, telephony, wireless, tools and help
You can notice a toolbar below the settings bar that contains many icons. So, basically, those icons are merely easy options for starting, stopping, and restarting packet capture as well as saving, reloading, opening, and viewing the recorded data.
The filter search toolbar, commonly known as the filter toolbar, is located beneath the toolbar. This toolbar will allow you to filter and search capture packets based on protocols, names, IP addresses, and other criteria.
Packet List Pane
A packet list pane, commonly known as the packets window, is located beneath the filter toolbar and displays all of the live collected packets.
Packet Details Pane
Following that, you’ll notice a white box with multiple dropdowns containing header information for chosen packets.
A window at the bottom displays the network interface name you’re currently using as well as the number of packets you’ve collected.
Understanding Color Coding
Another excellent and useful feature of Wireshark is colour coding. Understanding colour coding is essential for completing tasks quickly and efficiently. You might colourize your packets anyhow you want so that you can concentrate solely on them.
I’ve presented a variety of choices, features, expressions, and filters in this blog, but it’s impossible to cover everything in one blog, so I’ve included a fast Wireshark cheat sheet that will show you a variety of other things you can study and try on your own.
This blog covers practically all of the essential fundamentals needed to use Wireshark. I hope you have comprehended everything I have stated. Wireshark is a tool with a variety of functions that vary depending on how it is used.
