Wireshark - Getting Started with Wireshark

Updated:   |  Wireshark articles

Wireshark is a tool that can be used to analyze and visualize packets coming into and going out of a network interface. For example, let's say you have Wireshark on your laptop. Wireshark can be used to analyze and visualize the packets coming into and going out of your laptops network interface.

 

For example, let's say your laptop has IP address 192.168.0.140. In this example, Wireshark could be used to see the packets where the source is 192.168.0.140 which would be packets going out of your laptops network interface onto some other system and also packets where the destination is 192.168.0.140 which would be packets coming into your laptops network interface.


It is important to recognize that a packet almost always hops across a number of different systems. For example, a packet might go out of your laptops network interface and then onto a switch, then onto a router, then onto another router, and onto yet another router, then perhaps onto a firewall, onto yet another router, onto another switch, and finally onto a server. In this scenario, if Wireshark is being run on your laptop, you can analyze and visualize the packets coming into and going out of the network interface on your laptop, but this wouldn't show you what happens with the packets as they are hoping across the other various devices.
