Angry IP Scanner is a network scanner that much faster and simpler to use. It scans IP addresses and ports and is cross-platform and easy to use.
Angry IP Scanner can scan IP addresses in any range as well as any their ports. It does not require any installation. The application works by simply pinging each IP address to check if it’s alive, then optionally it resolves its hostname, determines the MAC address, and scans ports. Plugin support also allows for the amount of gathering data about each host to be extended.
The feature of Angry IP Scanner
- Favorite IP address ranges.
- Web server detection.
- Customizable open.
In order to increase scanning speed, the application uses a multi-threaded approach: a separate scanning thread is created for each scanned IP address. Scanning results can be saved to text, excel or IP-Port list files.
The application detects the ports that a computer has open. When a system is found, its address is shown on the screen. The user can perform different actions on it as long they are allowed: see the shared files, access its Web or FTP server, ping or launch Telnet.

Please note that while theoretically Angry IP Scanner can be used by crackers, in fact it was not intended for doing so, thus the lack of stealth scanning methods. Please do not consider Angry IP Scanner as a ‘hacktool’ or something similar.
