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.
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.
- IP filtering (Geofencing)
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.
