Anycast DNS – The foundation of a fast and reliable DNS service

Anycast DNS is an amazing routing solution that provides a large number of benefits. In case you are on the hunt for a great DNS service for your new website, or you need improvement in the performance of your domain, then for sure, you should check Anycast DNS! Let’s explain a little bit more about this amazing technology! 

What is Anycast DNS?

Anycast DNS is a traffic routing method that delivers website content quickly by placing your IP address and DNS information on several nodes.

That way, multiple DNS servers hold the data for your domain name in various geographical locations, and when a DNS query appears, all of them can answer it. Typically, the nearest server responds and provides the needed information – IP address.

Anycast DNS also guarantees that if one server from the group fails and it is not able to serve its purpose, the rest will handle the load. That is why it is a fantastic solution for better and faster DNS resolution and for improving the loading time, waiting for a response, and more.

How does it work? 

Anycast DNS directs DNS queries so that they receive the quickest answer. But how does it actually achieve that? Let’s find out! 

  1. A group of different name servers informs that they hold an identical IP address for a domain name. 
  2. A user types the domain name in its browser and triggers the DNS resolution process. The DNS query is initiated. 
  3. The Recursive DNS server obtains the DNS request and defines the route by choosing the shortest path to the closest name server holding the needed IP address.
  4. The Recursive DNS gets back to the users with the obtained answer, and the user is able to explore the desired website.

Anycast DNS can be configured to route requests based on the following: 

  • Time to response

  • Overcrowding of the route
