Plaintext-based DNS domain name resolution poses significant privacy risks. Therefore, encrypting DNS communication across all pathways is essential for privacy preservation. The IETF has standardized DoT, DoH, and DoQ to achieve encryption between end terminals and DNS full-service resolvers. Currently, an Internet-Draft has been published for encrypted communication between DNS full-service resolvers and authoritative DNS servers. However, the probing policy on the Internet-Draft prioritizes compatibility and conducts plaintext communication until it discovers authoritative DNS servers that support encrypted communication. Therefore, the Internet-Draft’s probing policy does not provide complete privacy preservation. In this paper, we propose a novel authoritative DNS server discovery approach that achieves privacy preservation while ensuring compatibility.
