Our everyday contacts, both personal and professional, are now reliant on network communication in the digital age. Understanding how to efficiently capture and evaluate data packets is essential as data travels via networks. With an emphasis on the popular network packet analysis program Wireshark, this paper examines the methods and resources for gathering and analyzing data packets. We go into details about the features that can be found in Wireshark’s data packet analysis, including traffic profiling, protocol analysis, and filtering. Proven use examples are showcased to show how Wireshark may be utilized by researchers, network administrators, and security experts to identify abnormalities, diagnose problems, and improve network efficiency. Moreover, this report includes a detailed analysis of the Hypertext Transfer Protocol, Domain Name System, and Internet Control Message Protocol. It illustrates how Wireshark may be used to analyze and understand the data packets of these three crucial protocols, emphasizing their intricate details, facts, and salient characteristics. Additionally, we have shown how to use Wireshark to capture passwords.
