DNS over HTTPS
- Gary Leicht
Owned by Gary Leicht
DNS over HTTPS (DoH) is a protocol whose purpose is to increase user privacy and security by preventing eavesdropping and manipulation of DNS data by using the HTTPS protocol to encrypt the data between the DoH client and the DoH-based DNS resolver. DoH traffic is indistinguishable from regular HTTPS traffic. The most common implementation of DoH occurs between the browser and a cloud DNS provider, not the OS resolver and the ISP’s DNS service. DoH protects the DNS communication between server and client.
