Android
The application for Android phones and tablets is installed from Google Play. It routes the device’s DNS traffic through a local VPN that the application creates on the device. The traffic does not leave the device through a VPN server. The interface only serves to capture DNS queries.
First launch
On first launch the application asks for a registration code issued by an administrator from the administration portal. The code is 8 characters long, consists of uppercase letters and digits, and is entered character by character into the fields below the Enter the registration code heading. The Send button verifies the code and the application moves on to its main screen.
Main screen
The main screen shows the current status of the service:
| Status | Description |
|---|---|
| Active | DNS PATROL is running and malicious traffic is blocked, a key icon is shown in the status bar |
| Inactive | DNS PATROL is not running, queries are handled by the device’s default DNS |
The available buttons depend on the status:
| Button | Function |
|---|---|
| Refresh | Reloads the status of the service |
| Stop | Stops a running DNS PATROL (the Active status) |
| Start | Starts DNS PATROL (the Inactive status) |
Starting up and permissions
The first time Start is tapped, the application warns that it needs permission to set up a local VPN in order to encrypt the device’s DNS queries. The Proceed button continues the start-up.
The system Connection request dialog follows, in which Android asks for the VPN to be allowed. It is confirmed with OK.
If the application does not have background data enabled, another dialog points it out. Restricting background data can lead to a loss of connectivity, because the application cannot serve DNS traffic while it is not in the foreground. The Proceed button opens the system App battery usage settings, where the restriction is lifted with the Allow background usage toggle.
Clearing the application data
If the device needs to be registered again, that is with a different registration code, the application can either be uninstalled and installed from Google Play again, or its storage can be cleared, which is faster.
In the device settings, select Apps.
Choose DNS PATROL from the list. From here the application can be removed with the Uninstall button. To clear the data, continue to Storage and cache.
Select Clear storage.
Confirm the dialog with Delete. The next time it is launched, the application asks for a registration code again.
The original device record stays in the portal under Access control > Devices, where it can be deleted.
Reporting issues
Problems with the application or with websites and applications being unavailable are handled by the organisation’s IT support.
