Benefits of using Anycast DNS

Anycast DNS – What is it?

Benefits of Anycast DNS are numerous. It provides multiple servers, all of them positioned in various geographical locations that store a particular IP address. The DNS records for a domain name are copied on not one but several servers. Depending on your needs, you are able to choose how many servers to store your information and improve your overall presence.

With Anycast DNS, the server that is nearest to the user will respond to the request. If a particular server is down for some reason and is unable to answer requests, the others will handle the workload. Thus, your website will remain reachable.

How does it work?

Anycast network routing can route arriving demands across many data centers. Every request appears in a single IP address that corresponds with the Anycast network. From there, the network distributes the data depending on the priority. Selecting the data center nearest to the user and reducing latency are the main factors for choosing an appropriate data center.
