Angry IP Scanner: A Cross-Platform Tool for Quick Network Scans
Angry IP Scanner is a simple but effective network scanning utility that’s gained popularity among system administrators and security analysts for one reason — speed. It’s open-source, works on Windows, macOS, and Linux, and doesn’t need a deep configuration before running useful scans.
Despite the name, it’s not “angry” at all — it just does the job fast, with a focus on usability and portability.
What It Can Do
| Feature | Function |
| IP range scanning | Detects live hosts using ICMP (ping), TCP, or UDP. |
| Port scanning | Supports basic port detection — typically used with TCP ping. |
| Hostname and MAC lookup | Resolves DNS and gathers MAC addresses if local. |
| Plugins support | Extend scans to pull NetBIOS info, web server banners, etc. |
| Data export | Results can be saved in CSV, TXT, or XML format. |
| CLI mode | Allows use in scripts or automation flows. |
| Cross-platform | Java-based; runs on almost any OS. |
| No install needed | Portable mode available — great for field kits. |
Where It Shines
– When you need to scan an unfamiliar subnet right now
– In environments where installing software isn’t possible
– On USB toolkits used for IT field work or audits
– As part of a larger scanning script for asset discovery
– For teaching basic IP/port scanning principles in labs
How to Get Started
1. Download from the official site
https://angryip.org
Choose the appropriate package for your OS.
2. Launch the application
On Windows and Linux, both installer and portable options are available.
3. Set scan parameters
Enter a range like 192.168.0.1–254 or a CIDR block. Set the ping method: ICMP, TCP, or UDP.
4. Configure ports
Default is 80, but you can scan multiple TCP ports — just comma-separate them.
5. Start the scan
You’ll get real-time results as hosts respond. MACs, hostnames, and port status appear in the table.
6. Export if needed
Use File → Save As to generate a report, or copy/paste results into a spreadsheet.
Notes and Limitations
– Scans are relatively basic — no banner grabbing, OS detection, or fingerprinting
– ICMP may be blocked on some networks, reducing effectiveness
– Results are not stored between sessions unless manually exported
– Not suitable for deep analysis or service-specific inspection
– Requires Java Runtime Environment (JRE) to run
Why It’s Still Widely Used
Angry IP Scanner is the kind of utility that doesn’t get in your way. It’s easy to explain, fast to operate, and requires almost no setup. Whether you’re a sysadmin verifying DHCP ranges, a pentester doing reconnaissance, or just someone figuring out “what’s online right now,” this tool delivers immediate answers.
It won’t replace a full asset management platform — but it’ll help you start one.
