DNS-based routing refers to a method of directing network traffic based on Domain Name System (DNS) queries, allowing for optimized routing decisions that consider factors like geographic location, server load, and availability. This approach improves user experience by delivering content from the nearest or most appropriate server, which is especially important for services that require fast and reliable access, such as Content Distribution Networks (CDNs). By leveraging DNS to manage how requests are resolved, it helps ensure that users receive data quickly and efficiently.
