Angry IP Scanner vs Kismet

Angry IP Scanner is a free, open-source desktop tool for scanning IP addresses and ports. It accepts address ranges, random addresses, or files in any format as scan input. The scanner checks whether hosts respond to pings and can optionally resolve hostnames, identify MAC addresses, and scan ports. It also supports NetBIOS information, favorite IP ranges, web server detection, and customizable openers. Java plugins can extend scanning and data gathering with fetchers, pingers, exporters, and feeders. Results can be saved as CSV, TXT, XML, or IP-Port list files, and a command-line interface is available. It runs on Linux, macOS, and Windows under GPLv2. The maker says installation is unnecessary and that the software can be copied and used anywhere. It is described as particularly useful to network administrators monitoring and managing networks. The FAQ notes that some antivirus vendors have flagged the older ipscan.exe, while saying version 3.x is not detected.

Kismet is a free, open-source wireless sniffer, intrusion detection system, wardriving tool, and packet capture tool. Depending on hardware and driver support, it can capture Wi-Fi, Bluetooth, Bluetooth LE, Zigbee, wireless sensor, airplane beacon, and power meter data. It runs headless as a standalone capture and wireless intrusion detection system, or with a web interface. Linux and macOS are supported directly; Windows use is through WSL. Remote capture forwards capture types over TCP sockets or websockets for centralized collection. Kismet’s kismetdb logfile combines packets, device records, location, and runtime data in an SQLite3-based file. A REST-like API offers JSON records, streaming pcap-ng, and websocket publish-subscribe endpoints. WIDS alerts can be connected through REST APIs, syslog, and some SIEM tools. The project says stationary use is most effective for WIDS; mobile or channel-hopping operation can reduce accuracy and coverage. Its macOS adapter support is limited, and WSL cannot access local hardware interfaces for packet capture, though remote capture is supported. The downloads page lists 2025-09-R1 as the latest stable release.
