Angry IP scanner is a very fast IP scanner and port scanner. It can scan
IP addresses in any range as well as any their ports. Its binary file
size is very small compared to other IP or port scanners. Angry IP
scanner simply pings each IP address to check if it's alive, then
optionally it is resolving its hostname, determines the MAC address,
scans ports, etc. The amount of gathered data about each host can be
extended with the available plugins.
It also has additional features, like NetBIOS information (computer
name, workgroup name, and currently logged in Windows user), favorite IP
address ranges, customizable openers, etc.
Scanning results can be saved 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.
In order to increase scanning speed, it uses multithreaded approach: a
separate threads is created for each scanned IP address.
This program is mostly useful for network administrators to monitor and
manage their networks.
