The Domain Name System (DNS) is a critical component of the Internet infrastructure, responsible for translating human-readable domain names into machine-readable IP addresses. However, the
increasing centralization of DNS traffic through large content-delivery hyper-giants (such as Google), coupled with the fact that the majority of DNS communication traditionally runs over unencrypted transports (UDP/TCP), has led to increased security and privacy concerns. In this talk, I will
present recent results on the resiliency and efficiency of DNS, the state of adoption of protocols that enable DNS privacy and their performance implications. I will conclude with a future outlook of a protocol design whereby traditional communications no longer have to trade performance for privacy, but can achieve the best of both worlds: privacy-enhancing DNS + secure communication on the Web.
