  "abstract": "Seldom have DNS protocol changes sparked such fierce debate as happen in the case of DNS-over-HTTPs (Doh) and it's little cousin, DNS-over-TLS (DoT). While for many people it is a matter of black and white, the reality out there is various shades of grey ;)\r\n\r\nThis talk will discuss the technical and political aspects of these DNS privacy protocols, where they come from, who is implementing DoH/DoT (both in the browser space and otherwise) and why it is a [good|bad] idea to support these protocol implementations.",
  "description": "Since the Snowden revelations, the <a href=\"https://datatracker.ietf.org/wg/dprive/documents/\">DPRIVE (DNS Privacy Exchange) working group</a> inside the IETF has been working on ways to make DNS, the Domain Name System, leaking less privacy related information (aka metadata).\r\n\r\nTwo new protocols from this working group are DNS-over-TLS <a href=\"https://tools.ietf.org/html/rfc7858\">RFC 7858</a> (DoT) and DNS-over-HTTPS <a href=\"https://tools.ietf.org/html/rfc8484\">RFC 8484</a> (DoH). Both protocols secure DNS queries between client systems and DNS resolver using encryption and authentication. DoT runs on a dedicated port 853, while DoH piggybacks on HTTPS (port 443).\r\n\r\nWhile DoT was initially mostly ignored by OS vendors, ISPs and users alike, DoH was adopted by browser vendors (Mozilla/Firefox and Google/Chrome) and created heated discussions among security and privacy experts. Even to the point that governments discussing way to outlaw DoH.",
