DHCP and Router Advertisement Options for the Discovery of Network-designated Resolvers (DNR)

Metadata

Publisher: IETF
Doc Type: Standard
Pages: 23
Abstract: This document specifies new DHCP and IPv6 Router Advertisement options to discover encrypted DNS resolvers (e.g., DNS over HTTPS, DNS over TLS, and DNS over QUIC). Particularly, it allows a host to learn an Authentication Domain Name together with a list of IP addresses and a set of service parameters to reach such encrypted DNS resolvers.
