Setting Quad9 Private DNS on Android

Android 9+ has a built-in Private DNS mode (DNS-over-TLS). No app, no root, no VPN config needed.

Steps

1. Open Settings → Connections → More connection settings → Private DNS
2. Select Private DNS provider hostname
3. Enter:

dns.quad9.net

4. Tap Save

Verification

Open a browser and visit https://dnsleaktest.com — it should show Quad9 (9.9.9.9) as your resolver, not your ISP.

Why Quad9

• Swiss jurisdiction — not subject to US CLOUD Act
• Zero-logging — independently audited
• DoT encrypted — your mobile carrier can’t see which domains you visit
• Blocks known malware domains by default

That’s it. One field, 10 seconds, encrypted DNS on all Wi-Fi and mobile data from your phone.
