What is the purpose of Anycast DNS?

Anycast DNS is a form of communication or routing technology that allows you to send and receive data more quickly. One IP address can be entered into several DNS servers around the world using this method. Any of them has the ability to react to the request. The goal is for the server that is nearest to the user in terms of distance to respond. This significantly speeds up the response time (DNS resolution).

Anycast DNS – How does it work?

Yes, Anycast DNS can boost your speed, but how does it happen? Users’ Domain Name System queries are routed to the nearest server for the fastest response thanks to Anycast Domain Name System. Here’s how it works in practice:

  • To begin, separate sets of name servers declare that they all have the same IP address.
  • The user then makes a request for a specific domain name, which initiates the DNS resolution process. The recursive DNS server receives the request and establishes the route by selecting the shortest way to the nearest name server that holds the required IP address.

We also use it to redirect requests based on:

  • Response time 
  • The server’s accessibility
  • Congestion on the highway
