DNS over HTTPS (DoH)

A protocol for performing DNS resolution via the HTTPS protocol. DoH encrypts DNS queries and responses, preventing eavesdropping and manipulation by network intermediaries. DNS queries are sent as HTTPS requests to a resolver (like Cloudflare 1.1.1.1 or Google 8.8.8.8) on port 443, making them indistinguishable from regular web traffic. DoH improves privacy but may bypass corporate DNS filtering policies.
