Masscan requires a packet capture library to function. You must install WinPcap or its modern successor, Npcap .

To scan a range for specific ports, use: masscan -p80,443 192.168.1.0/24 --rate 1000 .

After downloading the .rar or .zip from a source like GitHub, extract the masscan.exe .

Use the --banners flag to identify the service version running on an open port.

You can save results in various formats, including grepable text, XML, or JSON for easy importing into other tools.

Masscan is an ultra-fast port scanner capable of scanning the entire internet in under 6 minutes. While it is primarily a command-line tool, there are several ways to access a GUI-based experience or run it on Windows. Download & GUI Options

For a standard compiled .exe without a custom GUI, repositories like Arryboom's MasscanForWindows or WalnutMusic740's EXE Files provide pre-built binaries for Windows users.

A repository by Liosion offers a GUI version of Masscan compiled using Visual Studio 2015. This is often the primary source for users looking for a visual interface rather than the standard terminal.
