This is an example of the correct response:

The first underlined part shows the public IP address of your network.

The second underlined part shows the ID of your filtering policy that can also be found here - [https://www.safedns.com/cabinet/policy/](https://www.safedns.com/cabinet/policy/)

### Troubleshooting

If you haven't added the IP address to the SafeDNS Dashboard, the second underlined number will show “0”.

If the response contains the status message only, it usually means that DNS servers are not configured on your router or your device.
