Set Android Private DNS without breaking a hotel login page

Android Private DNS can send compatible DNS requests over an encrypted connection to a chosen resolver. A custom hostname may improve privacy from a local network, but a typo or blocked connection can make websites appear unreachable. Public Wi-Fi login pages can also complicate initial access.

Before you start​

Record the existing setting and obtain the provider hostname from its official documentation, not a social-media screenshot. If the phone belongs to work, check its network policy first.

Do it step by step​

1. Open Settings, Network & internet, then Private DNS or the manufacturer's equivalent. Note whether it currently uses Automatic, Off or a hostname.
2. Choose a trusted provider hostname and enter it exactly. Do not paste a normal website URL, IP address or unverified string into a hostname field.
3. Save and test several known sites on both Wi-Fi and mobile data. Confirm that the phone has internet access after reconnecting.
4. On a hotel or café network, complete the official captive-portal sign-in first. If access fails, temporarily restore the recorded setting and retry the network login.
5. After leaving that network, re-enable the intended Private DNS value and test again. Keep the provider name in a recovery note.

Check the result​

The setting should remain saved and browsing should work on the networks you actually use. A DNS test can show the resolver, but does not prove every app uses it identically.

If something goes wrong​

A VPN, corporate profile or local network can affect DNS behavior. If the device has no connectivity, revert to the recorded setting before changing unrelated router options.

Know the limit​

Encrypted DNS protects resolver traffic from some observers; it does not conceal the websites you sign in to or guarantee a safe destination. Google's Pixel network and Private DNS settings
