Secure DNS: Protect Your Browsing on Public Wi‑Fi
Learn why encrypting DNS queries protects your privacy on public Wi‑Fi and how to set up secure DNS with providers like Cloudflare, Quad9, and AdGuard.

We’ve all felt that annoying pause when a movie starts buffering on a coffee‑shop Wi‑Fi. The moment you hit play, your ISP can sniff every site you touch—even if the content itself is encrypted. That’s why people ask: should i use secure dns? The answer is a clear yes. DNS is the invisible hand that turns web names into numbers.
DNS works like a phonebook, but instead of human names it stores IP addresses. Traditional DNS sends that lookup in plain sight, so anyone on the same network can read it. Secure DNS—through DNS over HTTPS (DoH) or DNS over TLS (DoT)—wraps those queries in encryption, making the traffic look like ordinary web traffic. Picture your DNS request as a secret message in a bottle, hidden among regular chatter.
Why care? Every unencrypted DNS query leaves a breadcrumb trail for advertisers, governments, or curious snoops. Encrypting DNS keeps those breadcrumbs hidden, like a secret handshake between your device and the resolver. And the best part? It doesn’t slow you down—most providers add only a few milliseconds of latency.
Picking the right secure DNS provider is like choosing a reliable friend. You want someone who doesn’t log your secrets and respects your privacy. Reputable options include Cloudflare 1.1.1.1, Quad9, and AdGuard Public DNS. Cloudflare and Quad9 do not log queries, while AdGuard offers minimal logging and optional filtering for malware.
Next, the setup steps.
Windows On Windows 10/11, go to Settings → Network & Internet → DNS, then select “Use a private DNS” and enter the hostname (e.g., dns.quad9.net). If you prefer IP addresses, open Network & Internet → Status → Network and Sharing Center, click “Change adapter settings”, right‑click the active adapter, choose Properties, select Internet Protocol Version 4 (TCP/IPv4), click Properties, and set the Preferred DNS server to the provider’s IP.
macOS On macOS Ventura and later, open System Settings → Network, select your active connection, click Details, then add a DNS server (e.g., 1.1.1.1) and enable the “Use Secure DNS” toggle.
Android On Android 12 and newer, open Settings → Network & internet → Advanced → Private DNS, set it to “Private DNS provider hostname,” and enter the hostname (e.g., dns.quad9.net).
iOS On iOS 15 and later, go to Settings → General → VPN & Device Management → Private DNS, enable it, and enter the hostname (e.g., dns.quad9.net).
After configuration, test for leaks. Visit dnsleaktest.com or ipleak.net; the IP shown should match your provider, not your ISP. If you see mixed IPs, double‑check your router’s DNS settings—many routers still default to the ISP’s resolver.
Secure DNS only protects the lookup stage. Pair it with a VPN for full‑stack privacy; a VPN encrypts all traffic and masks your IP address. Together, they form a shield that’s both invisible and impenetrable.
Key Takeaways
- Secure DNS encrypts your lookup traffic, hiding it from eavesdroppers.
- Choose providers that log little to no data and offer DoH/DoT.
- Setup is straightforward on Windows, macOS, Android, iOS, and most routers.
- Always test for leaks; a clean test confirms your setup.

We’ve all felt that nagging annoyance when a video stalls or a site refuses to load. Often, the culprit is a tiny lookup that happens before the page even starts to fetch. The Domain Name System, or DNS, is the internet’s phonebook—turning names you can remember into machine‑readable numbers. When you type example.com, your device asks a DNS server for the IP address, and that request travels across the network in plain sight.
What is DNS?
DNS translates human names into IP addresses so browsers can find servers. It’s fast, reliable, and built into every OS. Yet, the original design never imagined privacy concerns. Every query leaves a trail that anyone on the same network—your ISP, a public Wi‑Fi hotspot, or a curious neighbor—can read.
Why is traditional DNS insecure?
Think of traditional DNS like shouting your address in a crowded room. Anyone nearby hears the location. Even if the content of your connection is encrypted with HTTPS, the DNS query reveals which site you’re visiting. That metadata can be used for tracking, censorship, or targeted ads. In short, plain‑text DNS is a privacy blind spot.
How secure DNS fixes the problem
Secure DNS protocols—DNS over HTTPS (DoH) and DNS over TLS (DoT)—wrap queries in encryption. They hide the request behind a secure channel, making it hard for eavesdroppers to see the destination. DoH blends DNS with regular web traffic, while DoT keeps it separate but encrypted. Both protect the lookup, but DoH is harder for middleboxes to block.
Choosing a private DNS provider
Not all DNS services are equal. A private DNS provider offers encryption, no‑logging policies, and sometimes content filtering. Popular options include:
Provider | Protocols | Logging Policy | Extra Features |
|---|---|---|---|
Cloudflare 1.1.1.1 | DoH, DoT | None | Fast, privacy‑first |
Quad9 | DoH, DoT | Anonymized | Malware blocking |
AdGuard Public | DoH, DoT | No logs | Ad and malware filtering |
These providers publish transparent privacy statements, so you can trust they aren’t hoarding your queries.
Forest VPN and Secure DNS
Forest VPN is a user‑friendly VPN that also offers built‑in secure DNS. By routing your traffic through its DoH‑enabled servers, it hides your DNS queries from ISPs and public Wi‑Fi providers. Users report that the VPN adds no noticeable lag, keeps browsing fast, and protects privacy without extra setup. Its affordable plans and wide server selection make it a convenient choice for anyone looking for a one‑stop privacy solution.
Why you should care
If you’re a casual browser, you might wonder, “Does it matter?” But consider this: every DNS query is a breadcrumb. A private DNS provider keeps those breadcrumbs private, reducing the amount of data that can be harvested by ISPs or governments. It’s a simple step that adds a layer of defense without sacrificing speed.

Should I Use Secure DNS? Traditional vs. Secure DNS: A Side‑by‑Side Showdown
If you’re wondering whether to shield your DNS queries from prying eyes, the short answer is yes. This guide walks through the differences between classic DNS and the newer, encrypted options like DNS over HTTPS (DoH) and DNS over TLS (DoT).
Traditional vs. Secure DNS
Classic DNS sends queries in plain text over UDP or TCP on port 53. It’s lightning‑fast, but anyone sharing the same Wi‑Fi hotspot can read the list of sites you’re looking up. DoH hides the request inside an HTTPS tunnel on port 443, so it blends in with regular web traffic. DoT opens a dedicated TLS connection on port 853, keeping the lookup encrypted but separate from HTTP.
Feature | Traditional DNS | DNS over HTTPS (DoH) | DNS over TLS (DoT) |
|---|---|---|---|
Transport | UDP/TCP 53, plain | HTTPS 443, TLS 1.2+ | TLS 853, TLS 1.2+ |
Visibility | Fully visible | Obscured behind HTTPS | Obscured behind TLS |
Blocking | Easy to block | Harder, but HTTP filters may stop it | Harder, requires TLS inspection |
Performance | Low latency | Slight TLS handshake delay | Slight TLS handshake delay |
Compatibility | Native everywhere | Native in macOS, Windows, Android, iOS | Native in macOS, Windows, Android, iOS |
ECS support | None | Optional | Optional |
Picture a public café: an attacker can sniff your plain DNS and discover you’re checking bank.com. In a corporate setting, the IT team can log every domain you query, even if the page itself is encrypted. Secure DNS stops both scenarios by encrypting the lookup itself.
Many people think DoH is just another VPN trick. It isn’t; it protects only DNS traffic, not the data that follows. That’s why a secure DNS setup should complement a VPN, not replace it. And even though DoH can look like ordinary HTTPS, it still carries DNS payload, so a DNS leak test is essential to confirm the query is truly hidden.
Quick test
Head over to <https://dnsleaktest.com> on a device that’s using DoH or DoT. If the IP shown matches your provider’s, you’re safe. If you see your ISP’s IP, you’ve leaked. A leak usually means the resolver is still using plain DNS or the router is overriding your settings.
Real‑world examples
- Android 12+: Set Private DNS to
dns.quad9.netand immediately stop seeing your ISP’s name in the leak test. - Windows 11: Toggle DNS over HTTPS in Settings > Privacy > Services.
- Routers: Enable Secure DNS under WAN settings to force all traffic through the encrypted resolver.

Should I Use Secure DNS? Step‑by‑Step Secure DNS Setup Across Devices
Secure DNS is like a secret handshake between your device and the internet. We’ve all seen a page stall while the browser hunts for an IP address. That tiny lookup can be sniffed by anyone on the same Wi‑Fi, turning your browsing habits into a public diary. So, should we lock it down? Absolutely. Let’s walk through a practical, device‑specific setup that keeps our DNS traffic encrypted and private. Forest VPN also offers built‑in support for DNS over HTTPS, ensuring your queries stay private even when you’re on a VPN.
Windows 10/11 and Windows Server
- Open Settings → Network & Internet → Status → Change adapter options.
- Right‑click your adapter, select Properties, then Internet Protocol Version 4 (TCP/IPv4) → Properties → Advanced → DNS.
- Click Add and type the IP of your chosen provider, e.g.,
1.1.1.1. - For DoH, go to Settings → Privacy → Services → DNS over HTTPS, toggle Enabled, then paste
https://cloudflare-dns.com/dns-query. - Apply, restart the adapter, and you’re done.
Do you wonder why we need to add both IP and URL? The IP handles standard DNS, while the URL tells Windows to tunnel queries over HTTPS, hiding them from local snoops.
macOS Monterey and later
- Open System Settings → Network, select your interface, then Details.
- Scroll to DNS and click Edit.
- Add the provider’s IP, then enable DNS over TLS or DNS over HTTPS in the same pane.
- Click OK, then Apply.
Mac users often forget the TLS switch; enabling it guarantees encryption even if DoH is disabled.
Android 12+
- Settings → Network & internet → Advanced → Private DNS.
- Choose Private DNS provider hostname and type
dns.quad9.net. - Tap Save.
Android’s single‑step interface makes it feel almost effortless, but double‑check that the provider’s hostname ends with .net or .com.
iOS 15+
- Settings → General → VPN & Device Management → Private DNS.
- Select Custom and enter
dns.cloudflare.com. - Confirm.
iOS automatically pushes the DoH request to the chosen host, so no extra steps are needed.
Popular Routers (Asus, Netgear, TP‑Link)
- Log in to the router’s web UI.
- Navigate to LAN → DNS Server or WAN → Secure DNS.
- Enter the DoH/DoT address (e.g.,
https://cloudflare-dns.com/dns-query). - Save and reboot the router.
Router‑level changes protect every device on the network, but remember to disable the ISP’s default DNS first.
Testing for Leaks
- Visit dnsleaktest.com and run the Quick Test.
- Check ipleak.net for WebRTC leaks.
- If the IP shown matches your provider, you’re safe.
- If you see your ISP’s IP, revisit the settings or check firewall rules.
FAQ
Will secure DNS slow my connection? Not noticeably. In most cases, the encryption overhead is minimal, and many providers offer fast, globally‑distributed edge servers.
Can I use multiple DNS providers? Yes. You can set a primary provider and a secondary fallback. Most systems allow you to enter multiple IPs or DoH URLs in order of preference.
Ready to lock down your DNS? Grab your preferred provider, follow the steps above, and enjoy a quieter, private browsing experience. For more on VPNs and online privacy, see our guide on VPNs for privacy.

Should I Use Secure DNS?
If you’re wondering whether you should use secure DNS, the first thing to do is make sure your DNS traffic is actually encrypted and not slipping out to your ISP or other third parties.
How to Run a DNS Leak Test
- Open a fresh browser window and go to https://dnsleaktest.com.
- Click Quick Test. When it’s done, hit Extended Test for a deeper look.
- On https://ipleak.net let the site auto‑scan. Both sites will show the DNS servers your device used.
- If you have a browser extension that forces its own DNS, make sure it isn’t active.
- If the test shows no results, your firewall might be blocking DNS queries.
- Close any VPN before testing to isolate the DNS path.
Reading the Results
- All IPs belong to your chosen provider → you’re safe.
- Mixed IPs → a leak.
- No DNS servers appear → your DNS traffic might be blocked by a firewall.
- A lone IPv6 address can indicate a fallback leak.
- A green checkmark next to the provider’s IP confirms encryption.
Click the Show DNS Server button to see the exact addresses. If the list shows your ISP’s IP, that means your DNS is still leaking.
Common Leak Triggers
- Running a VPN doesn’t automatically fix DNS leaks.
- Many routers forward DNS to the ISP even when a VPN is active.
- Some browsers use their own DoH servers, overriding system settings.
- Mobile OSes may fall back to cellular DNS when Wi‑Fi is weak.
- A mis‑configured proxy can expose DNS queries.
- Some VPNs route only HTTP traffic, leaving DNS on the local network.
- Public hotspots may override your settings with their own DNS.
- Corporate networks may inject DNS hijacking rules.
- Devices using IPv6‑only DNS can bypass DoH settings.

Ever wondered how a VPN can be the final shield after secure DNS? Picture the internet as a city, and every request you make is a car leaving a trail. A VPN wraps that car in a cloak of encryption, hiding both the destination and the driver’s address. We’ve seen how secure DNS keeps the lookup private, but the VPN keeps the rest of the journey invisible. It’s surprisingly simple and it’s free.
When you connect to Forest VPN, all traffic—HTTP, HTTPS, torrents, streaming—passes through an encrypted tunnel. That means your ISP or a corporate firewall sees only packet sizes, not content. The VPN masks your real IP, so sites see the VPN server’s address, not yours.
Secure DNS only encrypts the lookup step, while a VPN encrypts every hop. Think of secure DNS as a secret note sent to a post office, and the VPN as a secure courier that carries all your letters. When both are used together, the note never leaves the post office unseen, and the courier never drops a letter in the wrong mailbox. This layered approach is the gold standard for privacy.
