DNS over HTTPS
DNS over HTTPS (DoH) is a protocol for performing Domain Name System (DNS) resolution via HTTPS connections. It encrypts DNS queries and responses to enhance privacy and security by preventing eavesdropping and manipulation of DNS traffic. This protocol is typically implemented by web browsers and operating systems to protect user data from third-party interception.
Developers should learn and use DNS over HTTPS when building applications that require enhanced privacy, such as secure messaging apps, VPN services, or any system handling sensitive user data. It is particularly useful in environments with restrictive network policies or where DNS censorship is a concern, as it helps bypass traditional DNS blocks and ensures reliable, encrypted name resolution.
