DNS-over-HTTPS (DoH) sends the domain name (i.e. the address of the website) to a DoH-compatible DNS server using an encrypted HTTPS link rather than a plain text as previously used by HTTP.
DNS-over-HTTPS (DoH) allows third-party viewers to mask their DNS queries.
DNS over HTTP and HTTPS
DNS is still used by many networks for HTTP communications. DNS over HTTP communication makes it easy to send requests to servers using plain text. It leaves them open to attacks by third parties.
While DNS communication over the HTTPS protocol is encrypted using an integrated framework that provides data protection and security.
To Enable DNS-Over-HTTPS in Firefox:
