What Is Private DNS? – Private DNS is a built-in Android feature (introduced in Android 9) that lets you use secure, encrypted DNS servers instead of the default ones provided by your ISP or Wi-Fi network. It improves online privacy and security with minimal effort.
How Private DNS Works
Every time you visit a website, your device first sends a DNS query to translate the domain name (e.g., example.com) into an IP address.
By default, these queries are unencrypted and visible to your ISP.
Private DNS encrypts these queries using DNS-over-TLS. Your device connects directly to a chosen provider’s secure server, keeping the queries private and tamper-resistant. It works on both Wi-Fi and mobile data.
Benefits of Private DNS
- Enhanced Privacy: Prevents your ISP from seeing and logging every site you visit.
- Better Security: Reduces risk of DNS spoofing or hijacking attacks.
- Ad and Tracker Blocking: Some providers (like AdGuard or NextDNS) block ads, trackers, and malware at the DNS level.
- No Extra Apps Needed: Lightweight and system-wide on Android.
- Works Alongside VPNs: Adds an extra privacy layer or serves as a lightweight alternative.
Popular Private DNS Providers
- dns.adguard-dns.com — Strong ad and tracker blocking.
- 1dot1dot1dot1.cloudflare-dns.com — Fast and privacy-focused (Cloudflare).
- dns.quad9.net — Excellent malware and phishing protection.
- 8.8.8.8 or Google’s hostname — Reliable but less privacy-oriented.
- Custom options like NextDNS for advanced configuration.
How to Enable Private DNS on Android
- Go to Settings > Network & internet > Private DNS.
- Select Private DNS provider hostname.
- Enter the provider’s hostname (e.g., dns.adguard-dns.com).
- Tap Save.
The setting applies device-wide. Choose “Automatic” to use network-provided DNS when available, or “Off” to disable.

Private DNS vs. VPN
Private DNS encrypts only your DNS queries — lightweight and low battery impact. A VPN encrypts all your internet traffic for broader privacy and IP hiding. Use Private DNS for simple DNS protection or combine both for maximum security.
