Adaptive DNS Discovery (ADD) ==================================== Proposed Working Group Charter Sending DNS messages over encrypted transports, as defined in DNS over TLS (DoT) [RFC 7858] and DNS over HTTPS (DoH) [RFC 8484], provides benefits to the security and privacy of DNS data. Clients, such as applications and host operating systems, have started adopting these protocols to provide these user benefits. This working group will focus on discovery and selection of DNS resolvers by DNS clients in a variety of networking environments, including public networks, private networks, and VPNs, supporting both encrypted and unencrypted resolvers. It is chartered solely to develop technical mechanisms. Making any recommendations about specific policies for clients or servers is out of scope. Clients adopting encrypted DNS protocols need to determine which DNS servers support those protocols, and which server to use for specific queries if multiple servers are available. These decisions can vary based on the network environment, and also based on the content and purpose of the client queries. Network operators that start offering DNS encryption on their servers also need a way to indicate this support to clients. Communicating information about resolver configuration and behavior allows clients to make more informed decisions about which DNS servers to use. For example, a resolver may be able to resolve private or local names as a split DNS server. The Adaptive DNS Discovery (ADD) working group will work on the following deliverables: - Define a mechanism that allows clients to discover DNS resolvers that support encryption and that are available to the client either on the public Internet or on private or local networks. - Define a mechanism that allows communication of DNS resolver information to clients for use in selection decisions. This could be part of the mechanism used for discovery, above. - Develop an informational document that describes mechanisms for clients to detect specific network environments (such as captive portal and split horizon) and to use that information to inform their DNS configuration. This working group will coordinate with dnsop, doh, and dprive for any changes required in DNS protocols and will make sure that those groups are included in major document reviews at appropriate times. It will also work with capport to ensure that solutions are applicable to captive networks.
