Angry IP Scanner

Angry IP Scanner is an open‑source, cross‑platform utility that quickly scans IP addresses and ports across any specified range, including local networks, random selections, or lists imported from files. It presents results in a tabular view and can export the data to multiple formats, while also offering a command‑line interface for scripting and automation. The tool’s extensibility is provided through a plug‑in system that allows additional data fetchers to be integrated, enhancing its capability beyond basic host discovery.

The software is aimed at network administrators, IT professionals, and individuals who need to map or audit network resources. Its simplicity and speed make it suitable for both large enterprises and smaller environments, and it has been adopted by a variety of organizations, including banks and government agencies, for routine network scanning tasks.

Distinctively, Angry IP Scanner combines a graphical interface with a lightweight command‑line mode, runs on Windows, macOS, and Linux without requiring installation, and is distributed under a free and open‑source license. Its long‑standing development history and broad user base contribute to its stability and reliability.
