Angry IP Scanner

Angry IP Scanner at a glance

Angry IP Scanner is a popular free, open-source, cross-platform network scanner for quickly finding live hosts and open ports — a lightweight tool in the admin kit. It ships releases in an unhurried cadence; it's an occasional-use utility rather than a resident service.

For admins the update driver is compatibility and features rather than exposure — keep a reasonably current copy and source it from the official site. Being Java-based and cross-platform, it runs on Windows, macOS and Linux. The authorization caveat applies: scan only networks you are permitted to test, since port scanning others' networks can be unlawful. It runs with the user's rights and is often used portable, so watch for stale copies on technician machines. New versions bring scanning and export improvements. For deeper analysis, pair it with fuller tools like Nmap. Patchletter surfaces new Angry IP Scanner releases.
