How to Enable Private DNS (Encrypted DNS) on Xiaomi for Safe Browsing
Private DNS (DNS over TLS) encrypts the domain name lookups your phone makes, hiding your browsing from your ISP and preventing DNS-based tracking.
What Is Private DNS and Why It Matters
Every time you visit a website, your phone asks a DNS server "what's the IP address of this domain?" By default, this is sent in plain text — your ISP can see every domain you visit.
Private DNS (DoT) encrypts these requests so:
- Your ISP can't see which websites you're looking up.
- Your requests are authenticated — DNS hijacking is prevented.
- Ad-tracking via DNS is blocked if you use a privacy-focused DNS provider.
Set Up Private DNS on Xiaomi HyperOS
- Settings → Connection & sharing → Private DNS (or search "Private DNS").
- Select Private DNS provider hostname.
- Enter one of the following DNS hostnames:
| Provider | Hostname | Best For |
|---|---|---|
| Cloudflare | 1dot1dot1dot1.cloudflare-dns.com |
Privacy + speed |
dns.google |
Reliability | |
| AdGuard | dns.adguard.com |
Ad blocking + privacy |
| NextDNS | [your-id].dns.nextdns.io |
Custom filtering |
| Quad9 | dns.quad9.net |
Malware blocking |
- Tap Save — the phone shows "Private DNS active" when connected to any network.
Verify Private DNS Is Working
- Visit 1.1.1.1/help in Chrome.
- Check "Using DNS over HTTPS" → should show ✅ Yes.
- Or use the DNS leak test at dnsleaktest.com.
Private DNS vs. VPN
| Feature | Private DNS | VPN |
|---|---|---|
| Encrypts DNS queries | ✅ | ✅ (as part of VPN) |
| Encrypts all traffic | ❌ | ✅ |
| Hides IP address | ❌ | ✅ |
| Blocks ads (with AdGuard DNS) | ✅ | Depends on VPN |
| Battery impact | Minimal | Moderate |
Private DNS is a lightweight upgrade — use it alongside a VPN for maximum privacy, or alone if you just want DNS-level protection.
Troubleshooting
| Issue | Fix |
|---|---|
| "Can't connect to Private DNS" | Check hostname spelling; try a different provider |
| Websites load slower | Try Cloudflare (1dot1dot1dot1) — fastest DNS globally |
| Private DNS not available | Settings path varies; also check under Wi-Fi advanced settings |
Pro Tips
- AdGuard DNS (
dns.adguard.com) blocks ads at the DNS level across all apps — even apps without ad-blocking settings. - Private DNS applies to all networks (Wi-Fi and mobile data) — unlike VPNs which are per-network or manual.
- On HyperOS, Private DNS sometimes resets after a system update — recheck and re-enter if browsing feels less private.
