The Domain Name System (DNS) is one of the foundations of the Internet, yet most people outside of networking probably don’t realize they use it every day to do their jobs or check their email. Anycast DNS helps using the Internet to be even faster and efficient. Let’s talk about that a little bit more.
What is Anycast DNS?
When you choose Anycast DNS as your routing method, you can establish your IP address in several DNS servers.
Through Anycast, different servers positioned in many geographical locations are capable of answering the query. The closest of them will provide the IP address to the user.
Also, if one of the DNS servers is down for some reason, the second closest server will receive the request.
Experience is faster and better with Anycast DNS when we speak about loading time, waiting for a response, etc.
Before we continue, let’s explain a little bit more about what DNS is.
