DNS-over-HTTPS (DoH)

A technology for DNS data transmission and resolution using the secure HTTPS protocol. Unencrypted DNS lookups can be targeted by cybercriminals.

DoH provides the necessary data encryption using HTTPS as a tunnel.

One advantage of this method is that it performs better than traditional data exchange using a DNS server. DoH is a relatively new technology—Google and Mozilla included browser support for it only in 2018.
