It is widely used by network administrators and just curious users around the world
including large and small enterprises, banks, and government agencies.

The amount of gathered data about each host can be extended with plugins.

currently logged in Windows user), favorite IP address ranges, web server detection, customizable openers, etc.

Scanning results can be saved to CSV, TXT, XML or IP-Port list files.
With help of plugins, Angry IP Scanner can gather any information about scanned IPs.
