What is GeoDNS and how does it work?

What Is GeoDNS

Latency is one of our biggest enemies on the Internet. If a visitor needs to wait a long time for their result, they can get angry and leave the page. Not satisfied visitors means fewer sales and fewer chances to get them back. Luckily there is a service that can help you reduce the latency dramatically, and it is called GeoDNS

What is GeoDNS?

Between the request of a visitor and the response of the authoritative nameserver, there is a long way. That is especially true if the server is on another continent. What we can do to improve this process is to provide more nameservers, closer to the users, and have a system that redirects queries to the closest server. A smart load balancing mechanism that can locate the origin of the queries.

GeoDNS is a such a system that provides strategically located name servers on different continents and a process of distributing the traffic based on the locations of the queries. 

How does GeoDNS work?

When a user sends a query, a DNS server will analyze it, reading the IP. Based on this information, the query will be sent to the closest nameserver. This will reduce the waiting time significantly. 

Contrary to another popular solution called Anycast, the GeoDNS will provide distinct answers based on the IP of the user. Anycast is great, but GeoDNS is one step greater. 

Imagine this. You have servers in the USA, in Germany, and in India. A visitor from Italy will get the answer to its request from Germany. A Canadian will get it from the American server and a Chinese from the Indian. The traffic will be optimized for speed and load balancing.  

Who needs GeoDNS?

Anybody can feel the benefits of GeoDNS, but who exactly can get the most out of it? 

It is for global sites that will have traffic from different countries and substantial traffic: companies that need 100% uptime and low latency. 

E-commerce platforms that don’t want to miss a sale, Content companies, who needs a CDN network for fast content delivery on a global scale; Banking and Fintech companies with international clients, and more. 

It is for those of you that need to provide an excellent service on a global scale and don’t want to compromise.
