Notes and Permissions

• Permissions: The scanner reads ARP/neighbor tables and sends ping requests. Administrator/Root privileges may be required for accurate results in some environments.
• Subnet: The application automatically assumes a /24 subnet based on the local IP. You can customize the _local_net() function in scanner.py if needed.
