Hackers know this very well and take advantage to attack us.

Tags: , , , , , ,

​Some DNS background.

The DNS is a system of managing domains and IP addresses. It has a specific tree-like structure built with hierarchy.

Introduction to Anycast DNS

Tags: , ,

Anycast DNS explained.

Through Anycast DNS, several servers that are located in different geographical points can provide the same IP address. The DNS data for your domain name is duplicated on more than one server. You are able to choose a specific number of servers, depending on your needs. That way, your overall presence is going to be better.

When you are using Anycast, the most nearby server is going to answer the request of the user. In case one of your servers is offline due to maintenance or down for some reason, your website is still going to be reachable. The request will move to the second closest and available DNS server to resolve. As a result, the user’s request is going to be answered faster. Also, the overall experience is going to be improved in terms of loading time, waiting for a response, and so on.
