Something to look forward to: Despite being one of the most important elements in modern networking applications, the Domain Name System is still one of the internet's least secure technologies. Microsoft is looking to change the state of play by expanding the adoption of encrypted DNS traffic.
Microsoft recently announced that DNS over HTTPS (DoH) is now available on Windows Server 2025, providing encrypted DNS traffic for client-to-server communications. The feature has been available in Windows client editions for years and is now being extended to server-oriented versions of the operating system.
Microsoft notes that adding encryption support to DNS traffic can provide clear improvements in both network security and reliability. Previously available only as a public preview, the DoH feature is part of the Zero Trust architecture Microsoft is gradually implementing across its computing ecosystem. Zero Trust assumes that users and devices are not inherently trustworthy, which is why DoH adds an additional security layer by routing DNS traffic through HTTPS secured with TLS certificates.
