How can GeoDNS improve your performance?

What is GeoDNS?

You can find GeoDNS, also called global traffic director, or just traffic director. It is an effective approach for optimizing traffic to domains by implementing geographical-based routing. Additionally, it is considered a cloud alternative for load balancing. It has a positive effect on the performance of the network.

If you are running a business that distributes content all over the world, you could definitely benefit from it. GeoDNS provides you nameservers that are strategically positioned throughout the globe plus an efficient way to spread the traffic regarding queries’ locations.

How does GeoDNS work?

To start using GeoDNS, you want a DNS provider that supports Geolocation. Once you start implementing it, the DNS server is going to look for the location of every user’s query that is received. DNS checks the user’s IP address and searches for the location in the database. Then, the name server is going to send a pre-configured record defined explicitly for the country where the query arrived from. After GeoDNS identifies the query’s location, it determines the best and faster route to respond.

It utilizes DNS GeoIP searches to direct customers to the best server option, in other words, the one which is the closest location. As a result, every server will have different IP addresses for the corresponding domain. 

Advantages

Enabling GeoDNS for your domain provides some clear advantages.

  • Optimized traffic distribution

With GeoDNS, it is possible to manage the traffic wisely. It is a great solution for load balancing. It guarantees that the nearest nameserver will respond to the request of the visitor. Moreover, through this distribution, traffic overload is easy to avoid automatically.

  • Improved loading time

Quick loading is essential for improving the users’ experience and a critical factor in ranking in search engines. Moreover, based on the intelligent location method of GeoDNS, waiting time for sure is going to be lower for your visitors. That is already significant advantage. However, now that a positive user experience is also considered to be placed in the first search results, the gain is even more precious.

  • Improved uptime

Having a group of DNS servers is a great privilege. In case one server is down, the user’s request for sure is going to be resolved from one of the other servers.

Through IP filtering, you can deny access or direct users from a specific region. Let’s take, for example, a singer contracted exclusively with a British company. When there is a release of new songs, access to them can be restricted by IP filtering only for British users. IP addresses that are from other countries are going to be dropped.

Who can use it?

There are no limits when it comes to who can benefit from GeoDNS. All types of organizations could find it helpful. For instance, small websites that want to expand could like to use it. On the other hand, probably the biggest need of it has the large businesses to achieve stable process. It is considered that international organizations that handle a lot of traffic could get the most out of it.

Why should you choose Anycast DNS?

Anycast DNS explained

Anycast DNS is a traffic routing mechanism that delivers content fast from websites. It uses multiple nameservers that hold one individual IP address. 

Every one of the servers is located in a separate geographical location in order to be as close as possible to the users. The reason for that is to achieve a faster response to the request, which leads to a better user experience. The server that is nearest and available to the client requesting the website is going to answer. Any possibilities for latency are reduced to a minimum. Your website is easily reachable, and customers won’t wait long to connect with it.

Additionally, if the nearest server it’s not working due to maintenance, for example, another server, the next closest, is going to answer. 

Anycast DNS manages requests by the quickest route. For that reason, your domain’s resolution time becomes very еxpress. 

Benefits

  • Easy setup – You just have to configure it in only one server. Additionally, such settings can be expanded to the entire network.
  • Improved response time – With directing to the closest available DNS server, the response time is reduced.
  • DDoS protection – In case a DDoS attack appears, only a piece of the whole Anycast DNS group of servers is going to experience it.
  • Reliability – Implementing Anycast improves DNS reliability by establishing many servers in different locations with identical IP address. As a result, the service is more highly available and reliable because of the redundancy of the DNS servers. 

Why should you choose Anycast DNS?

If you are running an international business and your online presence is crucial, Anycast DNS is a great opportunity. Additionally, if you provide a service and you want speed and reliability in every location, you can benefit a lot from this type of routing mechanism. 

Anycast DNS manages the traffic in the most efficient way, plus your customers will be happy to reach your website easily. The improved network converts into a great experience and more sales.

Anycast DNS and CDN

Anycast DNS is a perfect choice for Content Delivery Network (CDN). The reason is its ability to quickly respond to queries and directing the traffic to a close local server.

Let’s picture an example network, where we have customers from 3 different continents: Europe, Asia, and North America. So, we established three copies of the website on three separate servers with different IP addresses. On every continent, we have set up Anycast DNS servers. So, therefore, all the traffic in North America is directed to the DNS server there. The traffic in Asia is directed to the Asian server, and the same runs for Europe.

The CDN is going to reduce the latency significantly for two reasons.

  • First, the Anycast DNS servers are as close as possible to the customers. They are positioned in each continent and even probably in each needed country. The domain is going to resolve very quickly.
  • Second are the several copies of the website. Thus, you are not just responding to the domain name query faster, although you can also manage the traffic to a closer web hosting.

When you combine these two, the customers are receiving the best experience. If the nameservers and web servers are located on different continents, the users will face latency for sure.
