This requires that the name server \_names\_ are in a DNSSEC signed zone. This also requires that the delegation of the zone served is protected by {[}I-D.dickson-dnsop-ds-hack{]}, since the NS names are the keys used for discovery of TLS transport support. Additional recommendations relate to use of various techniques for efficiency and scalability, and new EDNS options to minimize round trips and for signaling between clients and resolvers.}, }
