Angry IP scanner is a very fast IP scanner for Windows. It can scan IPs in any range.
Its binary file size is very small compared to other IP scanners.
Angry IP scanner simply pings each IP address to check if it's alive, then optionally it is resolving hostname, scans ports, etc.
It also has additional features, like NetBIOS information (computer name, workgroup name, currently logged in user and MAC address),
results saving to CSV, TXT, HTML, XML or IP-Port list file, can be used as a command-line utility in a batch file, etc.
With help of plugins, Angry IP Scanner can gather any information about scanned IPs.
Anybody who can write code is able to write plugins and extend functionality of Angry IP Scanner.
It is using separate threads for each scanned address to increase scanning speed.
It is free, so use it at your own risk. I am not responsible for anything you do using this program.
This program is mostly useful for network administrators to monitor and manage their networks.
Angry IP Scanner is an open source program Visit developing page: http://ipscan.sf.net/
