Angry IP Scanner: The Fastest Way to Know Who’s on the Network
Sometimes all it takes is a quick scan. No dashboards, no graphs, no overhead — just a fast sweep across the subnet to see what’s alive, what’s open, and what’s responding. That’s where Angry IP Scanner earns its name — and its reputation.
It’s a small, cross-platform network scanner that does one thing extremely well: ping a range of IPs, report what answers, and let you drill down if needed. It doesn’t care if the network is new, undocumented, or just plain messy — it gets the job done in seconds.
What It’s Known For
| Feature | How It Helps in Real Use |
| Ultra-Fast Scanning | Multithreaded scanning with real-time progress |
| IP and Port Detection | Shows live hosts, hostname resolution, open ports |
| NetBIOS and MAC Info | Displays NetBIOS name, MAC address, and vendor if available |
| Plugin Support | Extendable with user-written fetchers (e.g. for web servers, banners) |
| CSV, TXT, XML Export | Easy export for reports or audits |
| Cross-Platform | Runs on Windows, macOS, and Linux |
| No Installation Needed | Portable version available — just unpack and scan |
Who Uses It (and When)
– Sysadmins who need a fast way to sweep IP ranges
– Support teams hunting rogue devices or identifying active DHCP leases
– Pentesters doing quick asset enumeration
– Anyone managing subnets in dynamic or BYOD-heavy environments
It’s often the first tool launched when troubleshooting connectivity or verifying what’s online — before heavier NMS tools even finish loading.
What You’ll Need
– Java Runtime Environment (JRE) — required to run the app
– Admin rights — only if you need deeper port scans or custom scripts
– IP range to scan — enter manually or pull from presets
That’s about it. No agent, no installer if using the portable build. It’s plug-and-scan.
Getting Started
1. Download the latest version
→ https://angryip.org/download/
2. Launch the app
Works on Windows, macOS, or Linux. Use the portable version if preferred.
3. Set the IP range
Choose a single subnet or define a custom range.
4. Click “Start”
The scanner begins pinging and reporting live results.
5. Review and export
Results can be sorted, filtered, and saved to file.
6. Optional: Add fetchers
Extend output with additional info (e.g. HTTP title, OS fingerprint).
What Admins Say
“Perfect for quick subnet sweeps — use it almost daily.”
“Faster than nmap when I just need to know what’s online.”
“Lightweight, portable, and surprisingly powerful when combined with custom fetchers.”
A Quick Note
Angry IP Scanner isn’t trying to replace full-blown scanners or asset management systems. It’s the tool you reach for when someone says “Is that device even online?” — and you don’t want to wait for an SNMP timeout to find out.
Fast. Focused. Frustration-proof.
