AWS – Amazon Route 53 announces IP-Based Routing for DNS Queries

Today, AWS announced the launch of IP-based routing for Amazon Route 53, AWS’s Domain Name System (DNS) cloud service. Route 53 provides customers with multiple routing options, such as geolocation routing, geoproximity routing, latency-based routing, and weighted routing to route their end users to optimal endpoints. With the addition of IP-based routing, customers are now additionally empowered to fine-tune their DNS routing approach based on the Classless Inter-Domain Routing (CIDR) block that the query-originating IP address belongs to, allowing them to leverage knowledge of their end user base to optimize performance or network transit costs.
