The device discovery service scans the network and returns a list of devices it finds. This allows you to easily find Litmus Edge devices and copy their IP addresses.

- Discovery is disabled on all interfaces by default. You can enable it at any time.
- Once enabled, Discovery scans all network addresses at one-second intervals. It may take time to scan an entire network.
- Scanning doesn't stop until it is disabled. If a device is not recognized after ten minutes, it is removed from the list.

To search for devices that are specific to device protocols and drivers, use the [Device Discovery Tool](docId\:N9jtAdKuUXNU_YNhq87x4).

**Important**: Litmus Edge enforces restrictions to prevent the following issues.

- **Security Alerts**: Because discovery regularly scans the network, security systems (such as Trojan detection systems) might flag this activity. To avoid security warnings, network scans are limited to one-second intervals, and devices are removed from the list after ten minutes of inactivity.
- **Missing Devices**: Discovery only supports subnet / 24 networks to limit the number of nodes to discover. This restriction prevents discovery from taking longer than ten minutes for each device.
