🧠 What is Wireshark?

Wireshark is an open-source network protocol analyzer that lets users capture and interactively browse traffic running on a computer network. It’s essentially a microscope for network packets. Originally named Ethereal, the tool has evolved into a must-have for:

• Network Troubleshooting: Identify bottlenecks, misconfigurations, and suspicious activities.
• Security Analysis: Investigate breaches, monitor for anomalies, and analyze attack patterns.
• Protocol Development: Debug and develop network protocols with in-depth packet data.
• Educational Use: Learn how network protocols like TCP/IP, HTTP, DNS, and others operate under the hood.

With its graphical interface, robust filtering capabilities, and cross-platform support, Wireshark has become the industry standard for packet-level analysis.
