Much like the Free IP Scanner made by Eusing, the primary function of this tool is to scan a range of IP addresses to check for live hosts and open ports. the app uses ICMP (Internet Control Message Protocol) pings to detect the presence of a host on the network and TCP (Transmission Control Protocol) or UDP (User Datagram Protocol) to scan for open ports.
How does Angry IP scanner work?
It works by pinging an IP addresses to see if it is alive. For addresses that are active, the tool resolves its host name, determines the MAC address, and then scans the address for open ports.
Additional plugins are also made available to help gather more data about each host. This tool uses a very small footprint. Requiring just under 1 MB for complete stand alone installation. Making it a nice Portable Network Administration tool to carry with you on a USB flash drive.

To use the Angry IP Scanner, you simply need to specify the IP range that you want it to scan, and the tool will start sending out ICMP requests to each IP address in the range. When a live host is detected, the tool will attempt to connect to the host and scan for any open ports.
The tool also allows you to customize the scan parameters, including the maximum number of threads to use, the timeout for connections, and the types of protocols to use for scanning. This makes it a flexible and powerful tool for network administrators and security professionals to detect and diagnose network issues and security vulnerabilities.
