What is DoHĭoH is one of two emerging methods (the other being DoT) to encrypt the DNS traffic - which in this case is between your browser and the CIRA DNS resolver (or server). As a result, the IETF created new standards for DNS privacy – including DoH. The internet of old was built on utopian principals and, that utopia has been strained of late. ![]() The entire (original) point of the internet was that it was a free and open, and where notions of privacy between two “conversations” did not exist. One of the features of the DNS is that all this information exchanges in the wild of the internet in clear text. What is wrong with the DNS that we need these new solutions? This flexibility it is one of the amazing things about the DNS - the user has choice. They do it to get more privacy, better performance, or even just because it is fun. Many people who work in IT, or who just generally like to play with technology, change this DNS setting, either on their router, operating system or browser. For most Canadians, this lookup originates at a server located at their Internet Service Provider at something called a recursive resolver. This is called the Domain Name System (DNS) and it is often described as the internet’s phone book. ![]() In order for this address to find its way to a server it needs to be translated into the IP address that a machine understands. What is the DNSĮvery time you click on a link or type an address into the browser you are using a link that is human-understandable. Before we dig into the mechanics it is first important to understand what it is doing. Since CIRA Canadian Shield supports both traditional IPv4 and IPv6 as well as the emerging DNS encryption standards, it was a natural fit.īy default, Firefox uses, DNS over HTTPs, which is more commonly referred to by its acronym, “DoH” in the community. It is another step forward by the organization as they make DNS encryption the default for the browser under their overall commitment to privacy. Mozilla is enabling CIRA Canadian Shield as the default trusted recursive resolver (TRR) for Canadian Firefox users.
