Angry IP Scanner

Angry IP Scanner is an open-source network diagnostics publisher whose single flagship utility has become a standard tool for administrators, penetration testers, and curious home users who need a rapid overview of active hosts on wired or wireless networks. The program combines multithreaded address sweeping with configurable port probes, resolving hostnames, MAC vendors, and NetBIOS information in seconds, then presenting results in a sortable table that can be exported to CSV, TXT, or XML for later analysis. Lightweight and Java-based, it runs portably from a USB stick on Windows, macOS, or Linux, making it convenient for field technicians who want to leave no installation footprint. Typical use cases include verifying which IPs are in use before DHCP re-scoping, spotting unauthorized devices on corporate Wi-Fi, checking that servers are listening on expected services, or simply mapping an unfamiliar LAN during a security audit. Command-line switches allow integration into larger automation scripts, while built-in fetchers for HTTP titles, favorite IP ranges, and custom plugins extend the scanner beyond vanilla ping-sweeps. Because the codebase is GPL-licensed, community contributors continually refine performance and add new protocol detectors. Angry IP Scanner’s software is available for free on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, always installing the newest release and supporting batch installation alongside other utilities.
