From your Xbox One homescreen, click on Settings tab and click on Network.
Click on Advanced settings.
You should be in the Change Settings page.
On the right hand side of the menu, you will be able to see both your Primary DNS and Secondary DNS.
If the Primary DNS lists the same DNS as your Gateway, it could be that MyDNS has not been set up on your device.
If this is the case, please follow the instructions in our Xbox One setup guide below to set up MyDNS on your device.
If you are still having problems, please email us at [email protected], and try to include any errors and a full description of the fault.
We’ll get back to you as soon as possible.
