Wireshark4.6.9

Wireshark captures and inspects network traffic, letting you see individual packets and follow how communications move through protocols instead of treating network activity as an opaque stream. It presents packet details at a fine-grained level so you can investigate what is happening on a network and understand protocol behavior.

You can examine live communications or open saved capture data, then narrow the view with display filters and inspect decoded fields through protocol dissectors. Packet coloring, stream following, statistics, and export options help turn a large capture into evidence about a connection, exchange, or fault. Its protocol analysis supports diagnosing connectivity problems, validating network behavior, investigating suspicious traffic, and teaching how network protocols operate.

Networking professionals use it in operational, security, and research work, while educational institutions use it to demonstrate real protocol exchanges. The Wireshark developer community builds on work begun in 1998, with contributions from networking specialists around the world. Wireshark is open-source software, allowing it to be shared and examined under its license.

The Windows release is x64 and requires Windows 10 or later, or Windows Server 2016 or later. Version 4.6.9 focuses on bug fixes, including crashes in sharkd and in protocol or file parsers such as UMTS FP, RDP, Bluetooth, Kerberos, CMS, ERF, and BUSMASTER, along with fixes for reassembly and 3GPP phone-log handling.
