It continuously captures network transactions and displays them in an understandable format. Wireshark is commonly used for network analysis and investigation. Wireshark is the most widely used network protocol analyzer tool, formerly known as Ethereal.
We can store the Read and Write operation in file format. 
One of the important features is that it supports the Decryption of protocol. By using Wireshark, we can do a deep analysis of protocols. It provides a multi-platform to the users. It allows us to capture network traffic offline and Live. Basically, this is the most ideal and important tool, and it is used by testers and hackers to determine network traffic. Wireshark is included by default in Kali Linux and can be used immediately after installation. Kali Linux Wireshark provides a good display and network packets to display their content so that we can easily analyze them, and it supports most operating systems. ip.flags.Kali Linux is an open-source operating system used to implement security-related applications, and Wireshark is a free open-source tool used to determine and analyze network traffic while sharing data. When the devices on the path (routers, firewalls, switches, etc.) receive these packets, they check if they are larger than the MTU size, if so, the devices drop these packets, which causes failures. Some applications do not want their packets to be fragmented in the network. Filtering the Packets That Should Not Be Fragmented When we need to filter packets belong to only several hosts. We need that filter when we would like to see the packets coming and going to a network. Wireshark let you specify the network and its subnet length. Filtering broadcast and multicast packetsĪLSO READ: Steps to troubleshoot with TTL in Wireshark with Examples 6. Filtering an IP by the city, country etc. Filtering the packets that should not be fragmented. Filtering the packets larger than 1500 bytes (Default MTU size). Filtering conversations between 2 hosts. Filtering packets destined or sourced to/from a specific IP. Filtering a host by its destination IP address. Filtering a host by its source IP address. I will cover the topics below in the article. 
That is why being able to use the filters properly is very important. The primary benefit of the filters is to remove the noise (the traffic you are not interested in) and they help you narrow down the type of data you are looking for. It provides great filters with, which you can easily zoom in to where you think the problem may lie. Wireshark is a powerful network analysis tool for network professionals.
