DNS Load balancing explained

DNS load balancing is one very beneficial technique. If you are working with a website with a faulty and slow network will impact the experience of the end-users. To avoid a poor perception of the site and the whole organization, you could implement a load balancing method. Let’s explain more about how this technique does not allow a web server to overload.

What does DNS load balancing mean?

DNS load balancing is a popular technique applied for administrating the traffic of a hostname. It is an efficient and organized way to distribute the inbound network or application traffic over various servers.

How does Load balancing actually work?

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.

Get familiar with DNS Point of Presence (PoP)

If you are just about to start using a Managed DNS service for your domain, you have probably seen DNS Point of Presence (PoP) on most of the DNS provider’s pages. It is a very important feature that will show you where precisely the provider has name servers that you can use.

What is DNS Point of Presence (PoP)?

DNS Point of Presence, or DNS PoP for short, is a physical presence (name server) that you can use for your domain located at a specific place. The place is usually inside a large data center with important region connections.

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.

​Unicast DNS explained

To understand what Unicast is about, let’s briefly review the concept of routing. It’s a process of picking the most convenient path for the traffic in a network or across many networks.

If you think about networks, the Internet, for instance, there is constant communication. A continuous exchange of data that travels around, divided into packets. To deliver such an amount of data packets, from their source to their destination, definitely require a smart routing. 

Routing works based on routing information base (RIB) or routing tables. They are records of data that include the routes to different network destinations. Sometimes, they also have specific distances related to those routes. Administrators create these tables because they permanently monitor network traffic. Or they can be built through the routing protocols. That’s what they are made for.

There are different routing methods. Unicast is one of them.
