Instead of adding devices one by one, you can add IP Regex to Device Groups to assume every device with a matching IP address as the member of this Device Group. Similarly, some IP Regex Patterns can be added with the Deny rule, which makes the system deny all AAA requests coming from this IP.
To add an IP Regex Pattern to a Device Group:

1. Navigate to **Device Management **> **Device Groups**.
2. Right-click on the desired device group, and select **Add/Edit IP Regex Pattern**.
