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 DNS History

​History of Anycast DNS

Are you using Anycast DNS already? No? It is a great technology that took more than 30 years to get to today’s level. Now you will learn how exactly Anycast DNS was developed. 

​What is Anycast DNS?

Anycast DNS is a routing method that uses a simple trick – put the same IP address on all of the instances. Using it, you will have a network of Anycast DNS servers with exactly the same IP address. Yes, this is possible, and there is no network problem. What you are getting as a benefit is that whoever is searching your domain name will get the same IP address, no matter where in the world he or she is. Then the request will go on the way to this IP address, and since it is the same IP address, it will get a response from the closest Anycast DNS server there is. This will save time and provide redundancy since if one server is down, the request will simply travel a bit further and find another answer from the next Anycast DNS server on the network.

Anycast DNS CDN

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 (example.com) is translated into a computer language, an IP address (151.112.2.1). 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.

Anycast DNS DDoS attacks

How does Anycast DNS prevent DDoS attacks?

DDoS attacks keep spreading fear on the Internet. Attackers won’t stop targeting victims, therefore strengthening our security shield is a must. Anti-DDoS technology costs, but it’s worth the investment. Your online business can prevent or mitigate the threatening DDoS, and simultaneously its performance will be boosted! That’s the case with Anycast DNS. 

What’s Anycast DNS?

Anycast DNS is a mechanism for routing the traffic. It’s used for quick content delivery via individual IP addresses on all the different name servers included on a DNS network.

Benefits of using Anycast DNS

Anycast DNS – What is it?

Benefits of Anycast DNS are numerous. It provides multiple servers, all of them positioned in various geographical locations that store a particular IP address. The DNS records for a domain name are copied on not one but several servers. Depending on your needs, you are able to choose how many servers to store your information and improve your overall presence.

Anycast DNS and Unicast DNS: Differences

Anycast DNS explained

With Anycast DNS are established several servers, each of them in a separate geographical location, and they all can provide the same IP. Therefore, the DNS data about your domain name is duplicated on several servers.

The closest DNS server answers the request of the user. If one of the servers is not functioning, the next closest and available DNS server will answer the request. As a result, factors such as loading time, waiting for a response, and the users’ overall experience are a lot better.

Routing method

Anycast vs Unicast vs Multicast vs Broadcast

Routing communications on networks is a need! 

There’s a massive amount of data moving around every second. But data don’t travel randomly. They have an origin and must be delivered to a specific destination. So choosing the most convenient path for dispatching traffic is vital for efficiency and for avoiding chaos. Let’s see Anycast vs Unicast vs Multicast vs Broadcast.

Different types of routing methods have emerged to satisfy a wide variety of needs.
