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.
