So you want to start using GeoDNS. Congrats! That means your business is growing or already big.
Step 0. Know what GeoDNS is?
A Geographical Domain Name System or GeoDNS is a method to distribute the traffic considering the location where the DNS query was generated. GeoDNS involves a network of name servers located in strategic points of the planet. These servers have different IP addresses for the same domain based on the region or area they cover, and that represents an incredible speed boost for the DNS resolution.
The trick of GeoDNS is that it redirects the traffic based on the DNS clients’ IP addresses.

How to start using GeoDNS?
Step 1. Check your needs
Consider the real needs of your business. Analyze if you need such a network of multiple servers worldwide working for you. What’s your market? Do you have an international company or a very local one? GeoDNS is a great option for most businesses because it brings many benefits, like speed, efficient traffic distribution, IP filtering, quicker loading time, constant uptime, and redundancy!
But mostly, international companies use it because they receive a high volume of DNS queries 24/7 from clients around the world. Since the queries are produced in very different and far away locations, deploying GeoDNS makes total sense.
Step 2. Research DNS providers
Research different GeoDNS providers. Look for a quality and trustable service. And check that the locations it offers (network) are convenient to cover your specific market needs.
Step 3. Analyze the DNS plans
Analyze the different available plans of that provider. Don’t pay more for extras you don’t need. Calculate the number of DNS queries you expect to be sure the plan will cover your needs. Read carefully all the policies for payment, contract cancellation, technical support, the fine print, etc., not to be surprised.
Step 4. Configure your network
Once you get the service, your provider will run the GeoDNS, but you have to configure it on your system. You just need to add an IP address to every server in the world you choose to be close to your clients. It is easy. Just be careful while typing the IP addresses.
Step 5. Test
Run a test. Usually, the interface of most providers includes a tool to test (like Ping) what you configure and the changes you make. Test that the servers respond to the IP address you added to them.
Step 6. Your system is ready to start using GeoDNS
Wondering what will happen next? Well, when a user sends a DNS query to visit your domain, the DNS resolution process will be triggered, but this time, GeoDNS will make a big difference. The DNS server will read the IP address of the users to get their locations. Then, their queries will be sent to the nearest server to be processed. The answer to them will be quick, and the loading time will be reduced considerably.
Conclusion
GeoDNS is a great technology! If your company is steadily growing, already international, or if it is on the way to reaching that level, start using it today and enjoy its multiple benefits.
