About Angry IP Scanner
An independent resource dedicated to helping users discover, download, and get the most out of this powerful network scanning tool.
What Is Angry IP Scanner?
Angry IP Scanner (also known as ipscan) is a free, open-source network scanner designed to scan IP addresses and ports. It runs on Windows, macOS, and Linux, making it one of the most accessible network scanning tools available. System administrators, network engineers, and security professionals have relied on it for years to quickly identify devices on their networks, check for open ports, and gather hostname and MAC address information.
The software is written in Java using the SWT toolkit for its graphical interface. Despite being cross-platform, it feels native on each operating system. You can scan entire subnets in seconds thanks to its multithreaded architecture, and export results to CSV, TXT, XML, or IP-Port list formats for further analysis.
The Story Behind Angry IP Scanner
Angry IP Scanner was created by Anton Keks, an Estonian software developer and co-founder of Codeborne, a software development company based in Tallinn. The project started as a personal tool for network scanning and grew into one of the most downloaded network utilities on the internet.
The Beginning
Anton Keks developed the first version of Angry IP Scanner as a lightweight, fast IP scanning tool. Written in Java, it was one of the first network scanners to offer a simple GUI that worked across multiple operating systems.
Growing Popularity
The tool gained a loyal following among IT professionals and hobbyists. Its combination of speed, simplicity, and cross-platform support made it a go-to utility for quick network reconnaissance. Downloads climbed into the millions.
Complete Rewrite
Angry IP Scanner 3.0 represented a ground-up rewrite. The new version introduced a plugin-based architecture, improved scanning speed, better OS integration via SWT (replacing Swing), and a cleaner interface. It also moved to a modular design where custom data fetchers could be added.
Version 3.9.3 and Beyond
The latest release (v3.9.3, November 2025) bundles Java 17+ in the installer, so users no longer need to install Java separately. The GitHub repository has earned over 4,900 stars, and the project continues to receive regular updates under the GPLv2 license.
What Angry IP Scanner Does
At its core, Angry IP Scanner pings IP addresses to check which ones are alive, then gathers additional information about responding hosts. Here is what it can do:
Fast Multithreaded Scanning
Scans hundreds of IP addresses simultaneously using separate threads for each address, finishing subnet scans in seconds rather than minutes.
Port Scanning
Checks configurable port ranges on each host to identify running services like HTTP, SSH, FTP, RDP, and more.
Host Discovery
Resolves hostnames, detects MAC addresses, and collects NetBIOS information including computer names and workgroup membership.
Export Results
Save scan results to CSV, TXT, XML, or IP-Port list formats for documentation, reporting, or importing into other tools.
Plugin Architecture
Extend scanning capabilities with custom data fetchers. The plugin system lets you collect additional information beyond the built-in options.
Cross-Platform
Runs on Windows 7+, macOS (Intel and Apple Silicon), and Linux (x64 and ARM) with a native-feeling interface on each platform.
The Developer
Anton Keks
Anton Keks is a software developer, speaker, and co-founder of Codeborne, a software development company based in Tallinn, Estonia. He is known for his focus on clean code, test-driven development, and practical software craftsmanship. Beyond Angry IP Scanner, he has contributed to numerous open-source projects and spoken at conferences across Europe about software development practices.
Angry IP Scanner remains one of his most well-known creations, used by millions of people worldwide. The project is maintained on GitHub under the GPLv2 license, welcoming contributions from the community.
Why People Use Angry IP Scanner
Angry IP Scanner fills a specific niche: fast, no-fuss network scanning without the complexity of tools like Nmap or the limitations of Windows-only options like Advanced IP Scanner. Network administrators use it to inventory devices on corporate networks. Home users rely on it to see what is connected to their router. Security professionals use it as a quick first-pass scanner before running deeper analysis tools.
The fact that it is portable (no installation required for the standalone version), completely free, and works on all three major operating systems gives it broad appeal. You can drop the .exe on a USB drive, plug it into any Windows machine, and start scanning within seconds. That kind of convenience is hard to beat.
Its color-coded results table – green for alive hosts, red for dead, blue for hosts with open ports – makes it easy to visually parse scan results at a glance. And the favorites system lets you save commonly scanned IP ranges for quick access later.
