The UBNT Discovery Tool is a lightweight Layer 2 utility developed by Ubiquiti Inc. Its primary job is to discover Ubiquiti devices on your local network segment, even if they have conflicting IP addresses (for example, multiple devices with the default 192.168.1.20).
Version 2.3 is considered a "legacy gold standard" by many engineers. Unlike later versions that bundled Java-based interfaces, or much older versions that lacked modern security certificates, Version 2.3 strikes a perfect balance: it is stable, runs natively on Windows (without Java), and supports the transition from older AirOS to newer firmware.
