4. Network Scanner: Automatically detects all connected devices on your subnet, displaying their IP addresses, MAC addresses, and device names.
5. Low Resource Usage: Runs silently in the system tray without consuming significant CPU or RAM.
6. Portable Execution: No complex installation required in many configurations; run directly from a USB stick.
