WinPcap locates the Windows standards in packet access directly, thereby generating a split connection to unprocessed network data for software which include network monitors, protocol analyzers, network intrusion, security tools, routers, detection systems, network analyzers, and among others.

Network application requires only an essential operating system such as socket so that you can access data on a given network. In this situation, the details that are low such as protocol handling and packet reassembly is controlled by the operating software, which makes it easier for the request to be read on traffic that’s ongoing.

How Can WinPcap Help You?

The packet and network analysis on WinPcap acts as a device driver inside the Windows kernel’s network component together with a group of DLLs which set up an exploitable programming interface that’s easy for the category of the application which is being mentioned. The available dynamic libraries create a group of system-independent functions.

The system-independent functions are used for collecting various lists of available – detailed information, network adapters, sending and saving packets. This tool can also allow you to generate packet filters for a specific set of packets which are obtained. It helps you to capture raw packets and also those which are transmitted via network adapters and others replaced by different computers on shared media.

This software also makes use of defined rules to sort out the packets, send out a raw packet to the network, or retrieve statistical contents that exist. The program is known for connecting network and its Windows environments. Its library comprises Libcap Unix API but only in the Window feature, and it can also be used for marketable network tools and some open-source tools present on the web.

It can watch, diagnose, save disk network traffic based on different complex rules. It is very easy for every user to use because the tool is understandable. Thousands of people make use of it on a daily basis, and the details of the program of any files are documented. Its drivers have key features such as injection and packet capture, as well as more improved ones such as monitoring engine and programmable filtering system. 

The programmable filtering system can be used to stop a capture session to a given subset of network generated by a given host while the monitoring engine gives a commanding, easy to use a mechanism to get network load or the number of data which are swapped between two hosts.

The system captured must be able to export an interface that user-level application will be able to benefit from the features that the Kernel driver offers. This application offers two different libraries: wpcap.dll and packet.dll. The Packet.dll. Presents a low-level API which can be used directly to access other functionalities of the driver, with other programming interfaces from the Microsoft. The Wpcap.dll exports a more dominant set of improved level capture primitives which are well-matched with libpcap. These functions allow packet capture in a way which is self-sufficient of other network hardware. 

Key Features of WinPcap Include:

  • Free open source.
  • Tested and reliable.
  • Well documented.
  • Popular interface network.
  • Multi-platform.
  • Easy for final usage.
  • Proving of filtering engines.
  • Compatible with libpcap.
  • Provision of packet-capture.
  • Modification of application.
  • Implementation of classical optimizations.
  • Protocol analyzer.
  • Network monitors & detection systems.
  • Traffic generators & network testers.
  • Ability to run on every operating system.
  • Documented APIs.


WinPcap, which is an open-source application, can help you capture and transmits all your network packets without any configurations. It can also split your network data for different software and also collects a detailed list of information that you would like to know.
