An Encrypted DNS Resolverdiscovered in this manner is referred to as a "Designated Resolver".These mechanisms can be used to move from unencrypted DNS toencrypted DNS when only the IP address of a resolver is known. Thesemechanisms are designed to be limited to cases where Unencrypted DNSResolvers and their Designated Resolvers are operated by the sameentity or cooperating entities. It can also be used to discoversupport for encrypted DNS protocols when the name of an Encrypted DNSResolver is known.
