Oct 13, 2021Jonathan Hoyland, Christopher Wood

Summary
This post details Cloudflare's active participation in the IETF, contributing to the development and standardization of key internet protocols like DNS-over-HTTPS (DoH), Oblivious DNS-over-HTTPS (ODoH), QUIC, and TLS Encrypted Client Hello (ECH). These contributions aim to incrementally improve metadata privacy, advance architectural capabilities, and enable new use cases by developing and advocating for open standards.
