What DNS is and why it matters for Proton VPN users

DNS translates site names like example.com into IP addresses. Without DNS privacy, your ISP or anyone on your network can see which sites you visit.
Proton VPN aims to minimize leaks by routing DNS requests through its own DNS servers when connected, instead of using your device’s default DNS.
Real-world impact: a DNS leak can reveal your browsing targets even while you’re connected to a VPN, which is why DNS security is essential for privacy-conscious users.

Proton VPN DNS architecture: what you should know

Default DNS handling: Proton VPN routes DNS queries through Proton’s own DNS servers while the VPN tunnel is active.
Split-tunneling and DNS: If you enable split-tunneling, some traffic may bypass the VPN and use your device DNS, potentially causing leaks. Keep risky apps routed through VPN if privacy is the goal.
DoH and DoT options: Proton VPN supports DNS over HTTPS DoH and DNS over TLS DoT as an extra privacy layer, depending on platform and app version.
Gaming and streaming caveats: Some DNS configurations can affect latency or geo-restriction behavior. Test after changing DNS settings.

How to enable and configure DNS options in Proton VPN

Step-by-step quick-start Desktop app:
1. Open Proton VPN app and sign in.
2. Go to Settings > DNS.
3. Choose the DNS option:
  - Proton DNS default
  - DoH DNS over HTTPS if available
  - DoT DNS over TLS if available
4. Turn on the chosen DNS option and reconnect to any server.
5. Run a DNS leak test to confirm.
Step-by-step quick-start Mobile apps:
1. Open Proton VPN app on iOS/Android.
2. Tap the gear/settings icon, select DNS.
3. Enable Proton DNS or DoH/DoT as offered.
4. Reconnect and verify with a leak test.
DoH vs DoT: DoH tends to be more compatible with web browsers and apps; DoT is often simpler to enforce at the OS level. Choose based on your device ecosystem and privacy needs.
Compatibility notes:
- Not all devices support DoH/DoT at the OS level; in such cases, use the Proton VPN app’s DNS settings.
- Some networks like corporate networks or public Wi-Fi can interfere with DNS settings; in those cases, do not rely on DNS alone for privacy.

DNS leak testing: how to verify you’re protected

Why test: Even with a VPN, misconfiguration or a leak can reveal your activity.
Quick test methods:
- Visit dnsleaktest.com or dnsleak.com while connected to Proton VPN. If Proton DNS shows up, you’re protected.
- Use a browser extension to test WebRTC leaks, which can sometimes reveal IPs even with a VPN connected.
- Check your IP and DNS via multiple sites whatismyip.com to ensure the IP matches your VPN server and the DNS provider is Proton’s when connected.
Interpreting results:
- No leaks: DNS shows Proton servers or DoH/DoT endpoints you configured, not your ISP or local network DNS.
- Leaks detected: Recheck app settings, ensure all traffic goes through the VPN, disable IPv6 if your VPN doesn’t support it, and test again.

Practical privacy enhancements you can apply with Proton VPN

Disable IPv6 if you’re unsure your VPN supports it fully for all traffic.
Enable the most trusted DNS option Proton offers Proton DNS by default to minimize exposure.
Use DoH/DoT consistently on all devices to harden DNS privacy beyond just the Proton VPN app.
Enable kill switch and network lock: This keeps traffic from leaking if the VPN disconnects. Pair it with DNS protections for best results.
Consider a dedicated DNS privacy checklist per device:
- Desktop: Ensure DNS option is Proton DNS or DoH/DoT is active.
- Mobile: Confirm DoH/DoT enabled and app reconnect after setting changes.
- Router: If you route through a VPN-enabled router, ensure the router’s DNS settings don’t bypass the VPN tunnel.

Use cases: when DNS secrets really matter

Working remotely from coffee shops: Public networks are risky; DNS privacy helps avoid eavesdroppers correlating visits.
Privacy-first browsing: For users who want to limit trackers and domain lookups by third parties.
Bypass DNS-based censorship: Some networks filter sites using DNS-level blocking; DoH/DoT plus Proton DNS can help bypass blocks while staying within privacy best practices.
Streaming privacy: While streaming, you want your DNS lookups not to reveal your location or activity to local networks.

Technical tips and common pitfalls

Don’t mix VPNs with third-party DNS providers if privacy is your main goal. If you want extra privacy, DoH/DoT options with Proton DNS are preferable to third-party DNS.
IPv6 considerations: If you’re not sure your VPN handles IPv6, disable IPv6 on your device to prevent leaks via IPv6 traffic.
Device-wide vs app-specific DNS: App-level DNS settings might override system-level DNS for some apps. Prefer system-wide DNS configurations that apply to all apps in your privacy goal.
Firmware and router DNS: If you route your traffic through a VPN-enabled router, verify DNS behavior on the router itself; some routers may reveal DNS requests to the ISP if not properly configured.

Data and statistics to understand DNS privacy in 2026

A significant portion of VPN users report DNS leaks less often when using DoH/DoT compared to traditional DNS. General trend: privacy-focused DNS configurations are increasingly adopted among VPN users.
DoH adoption grew by double digits in 2025 across desktop browsers and mobile apps, signaling a rising demand for encrypted DNS transport.
VPN kill switch adoption remains critical: when VPN drops, DNS leakage protection via a kill switch can prevent exposure. A strong practice is to enable kill switch with DNS protections enabled simultaneously.

Comparison: Proton VPN DNS options vs other popular VPNs

Proton VPN:
- Pros: Strong emphasis on privacy, Proton DNS by default, optional DoH/DoT, solid leak protection, straightforward testing workflow.
- Cons: Some advanced DNS features may be less configurable on certain platforms.
Other VPNs for context:
- Some offer built-in DNS features, some rely on third-party DNS services, and a few require manual configuration for DNS leaks.
- Always verify the leak protection features and test after any changes.

Real-world setup scenarios

Scenario A: You’re on a laptop in a cafe
- Steps: Connect to Proton VPN, enable Proton DNS, run a DNS leak test, ensure IPv6 is disabled if not supported, use DoH on the browser if available.
- Expectation: Your DNS queries should resolve through Proton DNS, not the cafe network.
Scenario B: You’re on a home network with a router using Proton VPN
- Steps: Configure VPN on your router, ensure DNS settings on the router point to Proton DNS, enable DoT if supported, test for leaks from multiple devices.
- Expectation: All devices should have their DNS queries routed through Proton VPN’s DNS, minimizing exposure.
Scenario C: You need strict privacy for sensitive work
