Cloudflare 1.1.1.1 adds post-quantum DNSSEC validation

Cloudflare’s 1.1.1.1 public DNS resolver now validates DNSSEC signatures using ML-DSA-44, a new post-quantum algorithm. This enables testing of larger, quantum-resistant DNSSEC signatures at a global scale ahead of a wider rollout. Cloudflare aims for full post-quantum DNSSEC security by 2029, citing the need to prepare before quantum computers can break current encryption systems.

Why it mattersTransitioning DNSSEC to post-quantum algorithms addresses future threats from quantum computers potentially forging DNS responses. Early adoption and testing are key due to the technical complexity and ecosystem-wide changes required.
