Anycast DNS Network

Anycast DNS and GeoDNS comparison

Today, we’ll look at another fascinating topic: the comparison between Anycast DNS and GeoDNS. But first, let’s look at the definition of Anycast DNS, following by an explanation of GeoDNS. Then, finally, we’ll conduct a comparison between the two of them. So, let’s get down to business.

Definition of Anycast DNS

Anycast DNS is a communication or routing technology that speeds up data transmission and reception. Using this strategy, a single IP address can be typed into several DNS servers worldwide. Any of them is capable of responding to the request. The goal is for the server with the shortest distance to the user to respond. The response time is greatly sped up due to this (DNS resolution).

Anycast DNS – the foundation of a quality CDN service

The current demand for CDN service on the Internet is enormous. Graphics, documents, audio, video, scripts, you name it! Without efficient technology, it could be hard for a CDN (Content Delivery Network), and sometimes impossible, to satisfy users’ expectations worldwide.

What is DNS resolution?

DNS resolution is a vital process in which a requested domain typed in a human-friendly language ( is translated into a computer language, an IP address ( This process involves different servers to be accomplished. And no matter its complexity, it must take milliseconds to be considered efficient. 

Shortly described, every time you (user) request a domain, you type it on your browser. Your request is taken by a recursive server that will look for the corresponding IP address for the domain you requested. Without the IP address, the domain, nor any of its content, can’t be loaded.
