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 TXT, HTML, CSV, 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.

Angry IP Scanner is mostly useful for network administrators to monitor and manage their networks.

NOTE: Angry IP Scanner is free and open-source software, so use it at your own risk.

What's New in This Release: [ read full changelog ]

· bugfix: rescanning when display=alive or open does not properly render dead hosts
· appending from command-line is now supported
· feeder selection from command-line now also works
· some layout fixes, especially on windows
· cross-platform builds fixed: now all platform-specific code is isolated, so no more problems with mixing of 64-bit and 32-bit code
· Better following of Human Interface Guidelines: File menu renamed to Scan, because ipscan's primary job is not operating on files, some class renames as well for consistency
· bugfix: xfce is now correctly detected
· next bits of command-line usage implemented + some refactoring: FeederCreator introduced to reduce dependencies on AbstractFeederGUI
· Linux/gtk improvements: 64x64 icon is now used by default, WMClass is now set correctly to Angry IP Scanner (before SWT is initialized), so desktop launcher now can provide launching feedback and various docks will now handle launching properly.
· Mac buttons on Leopard now look right again (it seems that specifying non-default height for buttons makes them look flat) + removed the complexity of the default height
· MacOS Leopard Java updates that have broken ipscan's application bundle are now supported
· making Angry IP Scanner really translatable, Estonian example (incomplete) provided
· added support for button stock icons, linux version now makes use of GTK stock icons
· not changing the default button height on MAC, maybe it will make buttons appear the standard way under Leopard
· First bits of command-line support
· bugfix: still try to load the icon if it is not yet loaded
· bugfix: StatisticsDialog will no longer appear icon-less if the program was not active at the time of finishing
· use only IPv4 by default
· bug #2629462: allow exporting while scanning is in progress (with a warning message). This can be useful in case of synchronization or other bugs when scanning cannot be finished.
· question added to the end of crippled windows message
· setting pinger.windows as default for Windows
· dependencies fixed - deb package will now install on clean systems without java pre-installed
· FetcherPrefs interface introduced instead of Runnable
· HTTPSenderFetcherPrefs generified as PortTextFetcherPrefs
· SelectFetchersDialog now has the preferences button
· AbstractModalDialog now enforces stricter rules resulting in smaller subclasses
· refactoring: fetchers prefs introduced
· comments are now edited in the IP details window
