For instance, some Internet Service Providers offer family-safe filtering via DNS. In particular, with more than 35 years of history, a lot of additional services and features have been built on top of DNS. As DNS-over-HTTPS grows, it will put this concern aside because it benefits from the aforementioned HTTPS properties and sets a new reliable baseline to build upon.Ĭhanging how DNS works is a non-trivial task. Thus far, the unencrypted nature of DNS has meant that features that extend DNS could randomly fail due to causes such as network equipment that may drop or modify newly introduced DNS fields. The introduction of DNS-over-HTTPS gives the whole ecosystem a rare opportunity to start from a clean and dependable slate, making it easier to pursue further enhancements relying on DNS as a delivery mechanism. Unfortunately, DNS, on the other hand, until recently has remained unencrypted. It helps you browse or transact on the web without fear of having your credit card or personal information stolen by other internet users, even when using a public WiFi connection. Nowadays, the HTTPS protocol is almost ubiquitous and provides strong security and privacy guarantees. It took until 1994 for encryption to take-off with the introduction of the HTTPS protocol. There was no e-commerce, no online banks, and many people did not yet see a strong need for encryption on the web. When DNS was first introduced, the internet was in its infancy, and the web did not yet exist. When you want to access your favorite website, your browser first needs to determine which server is hosting it, a step known as “DNS lookup”. It’s the sort of change that requires careful planning and collaboration, which explains why it took us a little more than 2 years, gathering test data, listening to feedback, and addressing some misconceptions, to arrive at a design that put our users first with reasonable defaults and accessible controls. DNS-over-HTTPS introduces a significant change to the Domain Name System (DNS), a system designed more than 35 years ago that is central to how the web works even to this day. More concretely, Chrome will automatically switch to DNS-over-HTTPS if your current DNS provider supports it, and provide manual configuration options for users who wish to use a specific provider. With Chrome 83, we’ve started rolling out Secure DNS, a feature built on top of a secure DNS protocol called DNS-over-HTTPS, which is designed to improve your safety and privacy while browsing the web. ![]()
