In the vast and ever-evolving realm of the internet, the efficient distribution of web traffic is crucial to maintaining optimal website performance. One of the techniques used to achieve this is Round Robin DNS, a simple yet effective load balancing method that has been utilized for years. In this article, we will dive into the world of Round Robin DNS, exploring its workings, benefits, limitations, and best practices.
What is Round Robin DNS?
Round Robin DNS is a load balancing technique that distributes incoming web traffic evenly across multiple servers by alternating the order of IP addresses returned in the DNS (Domain Name System) resolution process. When a user attempts to access a website, their computer first contacts a DNS resolver to translate the domain name (e.g., www.example.com) into an IP address (e.g., 203.0.113.1) so that it can locate the correct server to retrieve the web page. In Round Robin DNS, the DNS resolver provides a list of IP addresses associated with the domain, but the order of the addresses changes each time a DNS query is made.
