How to Enable DNS over HTTPS (DoH) on Windows 11 with Dnsium

Windows 11 supports dns over https natively, giving you a straightforward way to encrypt every dns query your computer makes. When combined with a private dns resolver like Dnsium, you get both encryption and built-in ad and tracker blocking without installing extra software. Here's how to set it up, verify it works, and troubleshoot common issues.

Quick Summary: DNS over HTTPS on Windows 11

DNS over HTTPS encrypts dns queries for better privacy, wrapping them inside the https protocol so that intermediaries cannot read them. Before you dive into configuration, here's what you need to know:

  • Traditional dns requests travel in plain text to your dns server on port 53, exposing every domain name you visit to your ISP, wi fi network owners, and anyone else on the path.

  • DoH wraps dns traffic inside HTTPS on port 443, hiding domain lookups from passive observers on the network. DoH prevents eavesdropping on dns requests by third parties.

  • The windows 11 dns client supports system-wide DoH, which means most applications on your computer benefit from encrypted dns without any per-app configuration.

  • Dnsium provides encrypted dns over both dns over https and dns over tls dot, with built-in ad and tracker blocking. It is a paid public recursive dns resolver with a 30-day money-back guarantee.

  • At a glance: you get privacy from ISP snooping, security against dns spoofing, ad blocking at the dns layer, and all of it running at the operating system level.

What Is DNS over HTTPS (DoH) and How It Works

DNS is the system that translates a human-readable domain name like "example.com" into an ip address that your computer can connect to. Every time you open a website, your device sends dns queries to a dns server to look up that address. Traditional DNS uses unencrypted text on port 53 for requests, which means anyone monitoring your network can see exactly which domains you visit.

DNS over HTTPS (DoH) changes this by encapsulating dns requests inside the https protocol. DoH uses port 443, the same as HTTPS traffic, making dns queries indistinguishable from normal web browsing. DoH encrypts dns queries, preventing eavesdropping, and DoH blends dns requests with HTTPS traffic, hiding them from network-level observers. DoH traffic appears as normal web browsing to network observers.

When you use a doh enabled dns server like Dnsium, the process works like this: your dns client builds an HTTPS request containing the domain to resolve, sends it over TLS to the resolver, and receives an encrypted answer back. Only you and the resolver see the domain; intermediaries on the path see nothing but encrypted HTTPS packets.

Mozilla first implemented DNS over HTTPS in 2018, and since then, major operating systems and browsers have adopted it. DNS over HTTPS encrypts DNS queries using HTTPS protocol, and it's now one of the most practical privacy upgrades available.

For comparison, dns over tls (DoT) is another encrypted dns protocol. It also uses TLS encryption but operates on a dedicated port (usually 853) rather than blending with web traffic. We'll compare these in detail later.

Why Use DNS over HTTPS on Windows 11

There are practical reasons to enable dns over https on windows 11, especially when paired with a privacy-focused dns resolver like Dnsium.

  • Privacy. Setting up DoH prevents ISPs from seeing which sites you visit. DoH prevents Internet Service Providers from monitoring browsing history, and it stops public wi fi providers and local network administrators from logging your domain lookups.

  • Security. DoH makes man-in-the-middle attacks ineffective against dns queries. On untrusted networks like hotel or airport wi fi, this matters. DoH prevents ISPs and hackers from tracking dns requests.

  • Reduced tracking. DoH can hide dns traffic among other HTTPS requests, reducing the ability of advertisers and analytics providers to monitor your browsing at the network layer. However, be aware that malware can also exploit DoH to conceal dns traffic, which is why choosing a trusted resolver with filtering is important.

  • Ad and tracker blocking. When combined with Dnsium's server-side filtering, encrypted dns removes ads, trackers, and known malware domains before connections are even established.

  • No extra software needed. Windows 11's built-in support means no browser add-ons or vpn apps are required to encrypt dns for most applications on your computer.

Check Supported DoH Services in Windows 11

Windows 11 maintains a built-in list of known doh servers that are preconfigured with their DoH templates. These include major public resolvers like Cloudflare (1.1.1.1), Google (8.8.8.8), and Quad9 (9.9.9.9). However, you can still configure custom resolvers like Dnsium.

  • Open Windows Terminal or command prompt as an administrator. You can do this by right-clicking the start menu and selecting "Terminal (Admin)."

  • Run the command:

netsh dns show encryption

This displays preconfigured IPv4 and IPv6 dns addresses along with their DoH templates and auto-upgrade status.

  • Review the output: each entry shows the dns server address, whether DoH is supported, and the automatic template URL used for encrypted name resolution.

  • If Dnsium is not on the preconfigured list of known servers, you'll need to add it manually using PowerShell's Add-DnsClientDohServerAddress command (covered in Microsoft's documentation). This registers Dnsium's IP and DoH template so that the encryption options in the settings GUI become available.

Privacy-conscious users should consider a dedicated provider like Dnsium rather than relying solely on free public resolvers, which may not offer the same filtering or logging policies.

Step-by-Step: Enable DNS over HTTPS in Windows 11

You can enable doh per network adapter through windows 11 internet settings with just a few clicks. To enable DoH, go to Settings > Network & Internet.

  • Open Settings > Network & internet, then select your active connection-either "Wi-Fi" (then click your specific SSID) or "Ethernet."

  • Click hardware properties (or "Properties" depending on your build) and scroll down to the dns server assignment section.

  • Click "Edit," choose "Manual" from the drop down menu, and toggle IPv4 on. Select 'Manual' DNS settings to configure doh servers.

  • Enter your preferred dns and alternate dns server ip address values. As a placeholder example, you might use IPv4 addresses like 8.8.8.8, but replace these with Dnsium's actual server IPs.

  • Set the preferred dns encryption dropdown to "Encrypted only (DNS over HTTPS)" for both preferred and alternate entries. Enable 'DNS over HTTPS' in the DNS settings window.

  • Repeat for IPv6: toggle IPv6 on, enter Dnsium's IPv6 dns server addresses if available, and set encryption to DoH.

  • Click save and return to the connection properties page. Confirm that your dns servers now show "(Encrypted)" beside the IPs, indicating DoH is active.

Configuring DoH with Dnsium DNS Servers

This subsection focuses on using Dnsium as the dns resolver with windows 11 DoH for maximum privacy and ad blocking.

  • Replace generic dns addresses (like those from google or cloudflare) with Dnsium's production IPv4 and IPv6 server IPs in the Windows 11 dns settings.

  • Ensure the preferred dns encryption and alternate encryption dropdowns are set to "Encrypted only (DNS over HTTPS)" to enforce encrypted-only queries. This means the operating system will require doh for all name resolution.

  • All dns queries from the windows dns client will then be sent to Dnsium over HTTPS, with ads, trackers, and known malware domains filtered server-side before responses reach your computer.

  • Dnsium operates as a paid public recursive dns resolver with minimal logging and a 30-day money-back guarantee, differentiating it from free competitors.

Testing and Verifying DNS over HTTPS on Windows 11

After configuring doh, verify that dns traffic is actually encrypted and routed through the intended doh server.

  • Open command prompt and run:
ipconfig /all

Confirm that the listed dns server addresses match Dnsium's documented IPs.

  • Visit third-party encrypted dns test pages to verify that dns resolution is happening over HTTPS and not falling back to plain text on port 53.

  • In PowerShell, use:

Resolve-DnsName example.com

Check the "Server" field in the response to confirm queries are resolved by Dnsium's dns servers.

  • If Dnsium offers a dashboard or logging interface, check it to confirm that dns queries are being received over HTTPS from your windows 11 device.

  • You can also use pktmon to filter for port 53 traffic. If DoH is working correctly, you should see zero outgoing dns queries on that port.

DNS over HTTPS vs Standard DNS vs DNS over TLS (DoT)

Understanding the differences helps you choose the right protocol for your situation.

  • Standard DNS: Unencrypted UDP/TCP on port 53. Vulnerable to interception, spoofing, and profiling of dns queries. Your isp can see every domain you resolve.

  • DNS over HTTPS (DoH): Uses HTTPS on port 443. Blends dns traffic with normal web traffic, making it harder to block or filter. Natively supported in windows 11 and modern browsers.

  • DNS over TLS (DoT): Uses tls on a dedicated port (usually 853). Dns over TLS uses a different port than DNS over HTTPS, which makes it cleaner to separate from web traffic but also easier to block by port-based network controls. DNS over TLS is considered better for human rights in oppressive regimes where blending with web traffic may not be sufficient and dedicated secure channels are preferred.

  • Practical impact: DoH is more likely to traverse restrictive networks because it looks like regular HTTPS, while dot is easier for network administrators to identify and block.

  • Dnsium supports both DoH and dot, allowing users to choose based on device support. Use DoH on windows 11, and configure dot on routers or mobile devices that support it, while maintaining the same privacy and ad-blocking policy.

Configuring DoH in Browsers Alongside Windows 11

While windows 11 system dns settings protect most apps, browsers like Chrome and Firefox also have their own DoH options that can complement or override OS-level settings.

  • Google Chrome offers secure dns settings under Settings > Privacy and Security > Security. You can choose "With your current service provider" or specify a custom DoH provider. The browser validates the server's certificate to ensure secure communication. Align this with Dnsium when possible.

  • Mozilla Firefox has a built-in secure dns setting under Settings > Privacy & Security > DNS over HTTPS. You can point it to a custom doh server. Configure Firefox to use the same Dnsium resolver as your windows 11 system for consistent behavior.

  • Microsoft Edge inherits windows dns settings by default but also includes its own secure dns toggle. Leave Edge aligned with your system's Dnsium configuration.

  • If browsers are set to different doh servers than windows 11, dns queries may be split between multiple dns servers, complicating troubleshooting and making your filtering inconsistent.

When to Rely on OS-Level DoH vs Browser-Level DoH

The choice between configuring doh centrally in windows 11 versus individually per browser depends on your situation.

  • OS-level DoH with Dnsium is ideal for users wanting consistent protection across all apps, including non-browser software like email clients, game launchers, and system services.

  • Browser-level DoH is useful in managed or restricted environments (e.g., work laptops with locked-down computer configuration) where you cannot change OS dns settings but can at least secure browser dns traffic.

  • To avoid conflicts, ensure that if browsers use their own DoH settings, they target the same doh server configuration (Dnsium) as the OS. Double-encrypting through mismatched resolvers creates unnecessary network problems.

Troubleshooting DoH Issues on Windows 11

Misconfigured dns settings or incompatible networks can cause connectivity issues when you enable dns over https. Using DoH can bypass network security tools if misconfigured, so careful setup matters.

  • Verify that dns server IP addresses (IPv4 and IPv6) are entered correctly in windows 11 and match Dnsium's documented servers.

  • If your local network or isp does not support IPv6, disable IPv6 temporarily in your adapter's connection properties to see if that resolves dns resolution errors.

  • Flush the dns cache after changing settings:

ipconfig /flushdns

Run this in an elevated command prompt.

  • As a diagnostic step, turn "Encrypted only" back to "Unencrypted only" temporarily. If dns resolution works in plain text but not with DoH, the issue is specifically with doh server reachability-not basic connectivity.

  • Captive portals in hotels, airports, and cafés sometimes block external dns servers. Connect to the portal first using default dhcp-assigned DNS, then re-enable DoH with Dnsium afterward.

  • If issues persist, contact Dnsium support. As a paid service, Dnsium can assist with debugging your configuration and confirming doh server reachability from your network.

Dnsium: Private Encrypted DNS with Built-in Ad and Tracker Blocking

Dnsium is a public recursive dns resolver focused on privacy, encryption, and ad/tracker blocking for consumers who want more than what free time-limited or ad-supported resolvers offer.

  • Dnsium supports encrypted dns via both dns over https doh and dns over tls, protecting dns queries from interception across all your devices.

  • At the dns layer, Dnsium filters ads, trackers, and known malware domains-reducing exposure across your entire network without installing browser extensions on every device.

  • Dnsium maintains minimal logs and is designed for privacy-conscious users who want system-wide DNS protection on windows 11, routers, and mobile devices.

  • Unlike free competitors such as NextDNS, AdGuard DNS, Cloudflare DNS, Quad9, and Control D, Dnsium is a paid service with no free tier, backed by a 30-day money-back guarantee. You're the customer, not the product.

  • If you've just enabled DoH in windows 11, configure Dnsium's dns servers as your doh server to combine encryption with robust filtering and tracking protection.

Frequently Asked Questions about DNS over HTTPS on Windows 11

Is it good to use DNS over HTTPS on Windows 11? Yes. DoH provides stronger privacy by encrypting all dns queries, which protects against snooping on dns traffic by ISPs, network administrators, and attackers. For the best experience, pair it with a trusted provider like Dnsium that also filters ads and trackers.

Should I enable DNS over HTTPS if my ISP already provides DNS? Your ISP's dns is almost certainly unencrypted and logged. Switching to DoH with Dnsium gives you encryption, ad blocking, and minimal logging-none of which a typical ISP dns server offers.

Can I use DNS over TLS (DoT) instead of DoH on Windows 11? Windows 11 natively supports DoH through its settings GUI and group policy settings under administrative templates in computer configuration. DoT is generally configured on routers or other devices. Dnsium supports both protocols, so you can use DoH on your Windows PC and dot on your router.

Will DoH break my company's security tools? Possibly. Some corporate networks rely on inspecting dns queries for security and policy enforcement. Check with your IT department before enabling DoH on work devices. Use Dnsium on personal devices and home networks where group policy restrictions don't apply.

Does DoH make me anonymous online? No. DoH hides dns queries from intermediaries but does not replace a vpn or privacy-aware browsing habits. Your ip address is still visible to websites you connect to. DoH is one important layer of a broader security and privacy strategy-not a complete solution on its own.
