Скачать или смотреть DNS load balancing: How a DNS forward lookup works

DNS load balancing leverages DNS resolution to distribute traffic across multiple servers. Here's a step-by-step explainer of how the initial DNS forward lookup process works.

With the Domain Name System (DNS), the user device connected to the Internet can communicate with a specific website or web-based application, which then returns the requested information to the correct user, without the user having to recall the unique IP address of the requested resource.

DNS is used to do the grunt work of looking up the website or application name and translating the domain name into an IP address, which in return routes the client to its intended destination.

There are 9 steps needed to perform the DNS forward lookup and return the IP address of the desired website, outlined in this video.
