Understanding DNS and why it matters
- What DNS does for you: Domain Name System DNS translates human-friendly website names into machine-friendly IP addresses. Every time you type a URL, your device asks a DNS server to resolve it.
- The privacy risk: DNS queries reveal which sites you’re visiting to whoever operates the DNS resolver. Even if your traffic is encrypted via a VPN, leaking DNS queries can reveal your browsing patterns to your ISP, a government entity, or a malicious actor on the same network.
- DNS logs and retention: Some DNS providers log queries and can retain data for extended periods. That data, when combined with other telemetry, can enable profiling or correlation with other data points you generate online.
- The goal of DNS secrets: A robust DNS strategy keeps queries within trusted infrastructure, minimizes data exposure, and uses encryption to protect queries from eavesdroppers.
Proton VPN’s DNS features: what you get out of the box
- DNS leak protection: This feature ensures DNS requests are sent to Proton’s DNS servers or a configured trusted DNS resolver inside the VPN tunnel. If the VPN connection drops, the client is designed to prevent fallback to your ISP’s DNS, reducing the chance of leaks.
- Private DNS: Proton’s Private DNS is designed to route DNS resolution through Proton’s trusted servers, so your DNS queries don’t reveal your browsing to third parties.
- DNS over TLS DoT and DNS over HTTPS DoH options: DoT and DoH encrypt DNS queries, making it harder for anyone on the network to infer which sites you’re visiting based on DNS traffic alone.
- Automatic protection on all servers: When you enable Proton VPN’s DNS protection, most clients route DNS through Proton’s resolvers by default, regardless of which VPN server you connect to.
DoT vs DoH basics why you should care
- DNS over TLS DoT: Encrypts DNS queries between your device and the DNS resolver using TLS. It’s a dedicated channel for DNS, typically on a fixed port 853.
- DNS over HTTPS DoH: Encapsulates DNS queries in regular HTTPS traffic, making DNS lookups harder to distinguish from other web traffic. DoH typically uses port 443 to blend in with normal web traffic.
- Practical difference: DoH can be harder to block in restrictive networks because it shares the same port as standard HTTPS traffic, whereas DoT is more straightforward to inspect and regulate in some environments. Proton VPN supports these approaches to give you flexibility depending on your network constraints.
How to use Proton VPN’s DNS secrets effectively step-by-step
- Start with a clean install and the latest client
- Make sure you’re running the latest Proton VPN app on your platform. Updates often include critical security patches and improved DNS routing logic.
- On Windows/macOS/Linux/Android/iOS, enable automatic updates so you stay protected without having to remember to upgrade.
- Enable DNS leak protection and DNS routing to Proton’s servers
- Open the Proton VPN app.
- Go to Settings or Preferences.
- Turn on DNS leak protection. If offered, select Proton’s DNS servers or the “Private DNS” option.
- If your platform supports DoT or DoH in the Proton app, enable DoT or DoH as preferred. If you want to harden privacy, DoH is typically a strong choice on networks that allow HTTPS traffic freely.
- Save your settings and reconnect to a VPN server to apply changes.
- Decide on DoT vs DoH based on your environment
- If you’re on a network with heavy DNS-based blocking or throttling, DoH can sometimes help blend DNS requests with regular web traffic.
- If you’re on a more straightforward network and want simpler control, DoT can be a clean, efficient option.
- On mobile devices, DoH is often easier to enforce via the system DNS configuration. Proton’s client may offer a direct toggle for DoH/DoT.
- Verify DNS is in use
- After connecting, visit a DNS test site like dnsleaktest.com or dnschecker.org to confirm:
- The DNS resolver shown is Proton’s or the one you configured.
- There are no leaks that reveal your real IP address or ISP.
- Run a few tests from different locations or servers to ensure consistency across servers and time.
- Test on different devices and platforms
- Windows: Confirm that IPv6 traffic and DNS queries are routed through Proton’s DNS when the VPN is connected.
- macOS: Ensure the system’s DNS resolver is overridden by Proton’s DNS when the VPN is active.
- Android/iOS: Verify that the mobile OS respects the VPN’s DNS settings and that DoH/DoT toggles behave as expected.
- Linux: If you’re using a Linux client, check that systemd-resolved or NetworkManager routes DNS through Proton’s resolvers whenever the VPN is live.
- Use Kill Switch and other privacy controls in tandem
- Enable the VPN Kill Switch so that traffic doesn’t leak outside the secure tunnel if the connection drops.
- Consider enabling additional privacy features such as split tunneling to choose which apps go through the VPN carefully, so DNS requests for sensitive apps always route through Proton VPN.
- Combine Proton VPN with privacy-conscious browsing practices
- Use privacy-focused search engines and browsers that emphasize tracking protection.
- Enable HTTPS-Only modes where available, so you force encrypted connections whenever possible.
- Regularly review app permissions and installed extensions to minimize exposure.
Practical use cases for Proton VPN DNS secrets
- Public Wi‑Fi safety: At coffee shops or airports, DNS queries are particularly vulnerable. Proton VPN’s DNS protection minimizes the risk by ensuring DNS lookups stay inside Proton’s trusted path.
- Remote work and business use: For people who handle sensitive data, DNS privacy adds an extra layer beyond the encrypted tunnel. Your company can benefit from consistent DNS policy across devices used remotely.
- Circumvention and censorship environments: In places with DNS-based blocking, DoH/DoT can help by making DNS traffic harder to block and easier to route through trusted servers.
Tips to avoid common DNS privacy pitfalls
- Don’t disable DNS leak protection when you’re not sure about the network’s reliability. It’s tempting to rely on the VPN alone, but DNS leaks can occur during VPN reconnects or when switching servers.
- If you’re using heavy DNS caching or enterprise networks, give Proton VPN a moment to re-establish DNS routes after a server change.
- Be mindful of browser DNS configurations. Some browsers offer their own DNS settings or do-not-track-like features. these should be synchronized with your VPN settings to avoid conflicting routes.
What to know about Proton VPN’s privacy policy and DNS logs
- Proton positions itself as a privacy-first service with a no-logs policy for VPN sessions. When it comes to DNS data, the key claim is that DNS requests are resolved through Proton’s secure DNS infrastructure with privacy protection baked in.
- Always review the most current privacy policy and DNS-specific documentation because policies can evolve with new features or regulatory requirements.
- If you’re handling extremely sensitive information, consider layering Proton VPN DNS protection with additional privacy tools e.g., privacy-respecting DNS resolvers, tracking protection extensions, and careful network behavior on public networks.
DNS testing and validation: how to be confident
- Use multiple DNS test sites to ensure privacy controls are working across tools.
- Verify that the DNS resolver reported by the test aligns with Proton’s DNS servers when connected to Proton VPN.
- Perform a “kill switch off” test by temporarily disconnecting the VPN to see whether DNS queries spill over to your default ISP’s DNS, which should not happen if DNS leak protection is functioning correctly.
Advanced topics: DNS caching, logging, and residual exposure
- DNS caching can help speed up lookups, but it shouldn’t bypass protection. Proton VPN’s approach should ensure that the DNS resolver handles fresh queries without exposing your activity to third parties.
- Residual exposure can occur if DNS queries are embedded in other traffic or if apps bypass system DNS settings. The best practice is to keep DNS settings consistently under Proton’s control or DoT/DoH and enable a robust kill switch.
Privacy benchmarks and real-world expectations
- The VPN market is maturing, with more providers adopting encrypted DNS and leak protection as standard features. Expect ongoing improvements in speed, reliability, and privacy guarantees as the ecosystem evolves.
- Real-world privacy is about layers. DNS privacy is one critical layer, but it works best when combined with a strong VPN, updated software, secure browsing habits, and careful data minimization.
FAQ Frequently Asked Questions
Frequently Asked Questions
What is the difference between Proton VPN DNS and my ISP’s DNS?
Proton VPN DNS refers to Proton’s own or trusted DNS resolvers used behind the VPN tunnel, designed to minimize leakage and preserve privacy. Your ISP’s DNS is what you would normally use when you’re not connected to a VPN, which can expose your browsing queries to your ISP, depending on local laws and logging policies. Using Proton VPN DNS helps keep your DNS traffic within a privacy-centric network, reducing exposure to third parties.
How do I enable DNS leak protection on Proton VPN?
Open the Proton VPN app, go to Settings/Preferences, and toggle on DNS leak protection. If available, also enable DNS over TLS DoT or DNS over HTTPS DoH to encrypt DNS queries further. Save changes and reconnect to ensure the new settings take effect.
Can Proton VPN really stop DNS leaks on macOS and Windows?
Yes, when properly configured, Proton VPN’s DNS leak protection routes DNS resolution through Proton’s DNS servers or your chosen trusted DNS, preventing leaks even if the VPN connection experiences hiccups. Always run a DNS leak test after enabling protections to verify the setup.
Should I use DoT or DoH with Proton VPN?
DoT and DoH both encrypt DNS traffic, but they operate differently. DoT is a dedicated TLS channel for DNS, while DoH hides DNS queries inside regular HTTPS traffic. DoH can be more adaptable in networks that heavily inspect DNS traffic, but DoT can be simpler and highly effective on many networks. Choose the option that best fits your network environment and device compatibility.
How can I test whether DNS is leaking?
Use online DNS leak tests such as dnsleaktest.com or dnschecker.org while you’re connected to Proton VPN.
