Angry IP Scanner for Windows

Product snapshot

Angry IP Scanner is a lightweight, cross-platform network discovery tool designed for quick and simple scanning of IP ranges and hosts. It can probe IP addresses and ports across local and remote networks, quickly reporting which hosts are reachable and returning basic details about each device. The application is easy to download and install on desktop computers and aims to be fast and straightforward for both casual users and IT professionals.

Primary purposes

• Verify whether IP addresses are active or inactive.
• Identify hostnames and detect open ports on discovered devices.
• Collect MAC addresses and other host-specific data when available.
• Produce scan results that can be saved and shared for later analysis.

Notable capabilities

• Hostname
• Open ports
• IP address
• Ping response time

Additional captured fields can include:

• MAC vendor
• MAC address
• NetBIOS information
• TTL
• Filtered ports
• Site detector
• HTTP sender

Export formats and extensibility

Scan output can be exported into multiple formats to suit different workflows:

• XML
• CSV
• TXT
• IP-Port file

The program supports plugins to expand the data gathered for each host. Anyone familiar with Java can write plugins to add custom probes or parsers, allowing the scanner to be tailored for specific environments or reporting needs.

How scanning operates

Angry IP Scanner sends pings to IP addresses to determine whether hosts are alive. If a host does not respond to the configured ping method, it is typically marked as unreachable and the scanner will skip further probes for that address (this behavior is adjustable in the Scanning preferences). Each address is handled by its own thread, enabling multi-threaded scans that improve speed and efficiency.

Typical steps to run a scan:

1. Set the target IP range or hostname.
2. Confirm scan options and the ping method in Preferences.
3. Start the scan — results populate as hosts are discovered.
4. Use hotkeys or the context menu (right-click a host) to filter results, export data, or perform actions such as deleting or rechecking entries.

Security considerations and recommended uses

Angry IP Scanner can help identify poorly secured or unexpected devices on a network, making it useful for routine audits and troubleshooting. It is suitable for:

• Home users checking their local Wi‑Fi network
• Network administrators maintaining infrastructure
• Medium to large organizations performing asset discovery

Because the tool can probe hosts and ports, use it responsibly and with proper authorization on networks you own or are permitted to scan.

Summary

In short, Angry IP Scanner is a fast, extensible network scanning utility that offers multi-threaded discovery, multiple export formats, and plugin support for deeper inspection. Its straightforward interface makes it accessible for both beginners and experienced administrators who need a quick view of devices on a network.
