In the vast landscape of the Internet, where speed and reliability are crucial, the Domain Name System (DNS) plays a vital role. One particular advancement in DNS technology that has revolutionized the way we access websites is Anycast DNS. In this blog post, we’ll explore what it is, how it works, and its impact on performance.
Understanding Anycast DNS
Anycast DNS is a routing technique that allows multiple servers spread across different locations to share the same IP address. Unlike Unicast, where a single server handles requests, Anycast employs a network of servers geographically distributed worldwide. Therefore, when a DNS query is sent to an Anycast IP address, the request is automatically routed to the nearest server based on network proximity, ensuring an optimized and speedy response.
