About this tag
DNS over HTTPS (DoH) encrypts DNS queries between clients and resolvers, protecting against eavesdropping and tampering. On Windows, DoH is supported in Windows 10 and 11 for client-side encryption, and Windows Server 2025 now offers production-ready DoH for the DNS Server role, closing a gap where server-side DNS remained in cleartext. Performance comparisons show DoH can match or even beat plain DNS under good network conditions, though encryption overhead can sometimes increase latency. Security is a key concern: vulnerabilities like CVE-2026-3593 in BIND 9's DoH implementation highlight the need for timely patching. For enterprises, DoH is a step toward zero-trust networking, but it requires careful deployment to balance privacy, speed, and operational needs.

    Enable DNS over HTTPS in Windows 11 Without Mistaking It for a VPN

    Windows 11’s built-in DNS over HTTPS setting can encrypt the domain-name lookups that would otherwise be visible to a local network operator or ISP—but it does not stop an ISP from “watching everything” a user does online. As reported by How-To Geek, the setting is available under Windows 11’s...

    Windows 11 DNS: Why Alternate Servers Don’t Bypass Quad9 Blocks

    Windows users who configure a “Preferred DNS” and “Alternate DNS” server should not assume the second address is a clean, security-preserving failover path. Microsoft’s own DNS client documentation makes the key point: a negative response from a configured server can end the lookup rather than...

    Cafe Wi‑Fi DNS Test: Quad9 DoH Matches Speed, Beats Plain DNS

    A café Wi-Fi test comparing the network’s default DNS, Quad9 over plain DNS, and Quad9 over DNS-over-HTTPS found encrypted Quad9 lookups averaging about 21.5 milliseconds, nearly matching the café resolver and beating plain Quad9 DNS at roughly 46.3 milliseconds in that session. That result does...

    Encrypted DNS vs Speed: Why the Fastest Resolver Isn’t Always Best

    Encrypted DNS is a privacy upgrade that can lose badly in raw speed tests, as one MakeUseOf benchmark found when an ISP’s unencrypted resolver answered typical lookups in 38 ms while Cloudflare’s DNS-over-HTTPS took 167 ms from the same connection. The surprising part is not that encryption has...

    Does Windows 11 Fall Back to Plain DNS? DoH Privacy Settings Explained

    Windows 11 can encrypt DNS queries with DNS-over-HTTPS, but reports resurfacing in May 2026 argue that Microsoft’s client may still fall back to ordinary plaintext DNS under some conditions unless users or administrators explicitly require encrypted resolution. That makes the setting less of a...
