DoH
Abbreviation · Security & Infosec
Definitions
Short for DNS over HTTPS, a protocol that sends DNS queries through encrypted HTTPS connections instead of traditional plaintext DNS. It improves privacy and makes passive monitoring harder, though it can complicate enterprise visibility and policy enforcement.
In plain English: An encrypted way to send DNS lookups over HTTPS.
Example: "The browser was using DoH to a public resolver, bypassing the local DNS filtering policy."
