Understanding Recursive DNS server

by Pascal

Today, we will take a deep look at the Recursive DNS server. What is its primary purpose, its specification, and the types of lookups, we will explore now. So, let’s start.

Recursive DNS server – A detailed explanation 

The Recursive DNS server is in charge of looking up information. The purpose is to react to queries submitted by users. In technology terms, recursion refers to a method for resolving a problem. It entails a solution or program that will keep repeating until it achieves its purpose.

Consider it in this light. It functions as a link between authoritative servers and end-users.

This DNS server looks up a domain name’s IP address whenever it receives a request for it. It returns the proper IP address to the device or browser that originated the request once it gets it. Then, the machine receives the information and connects to the assigned IP address. Finally, the domain can be accessed.

DNS load balancing – Definition

DNS load balancing is a very commonly used technique for achieving the optimal management of the incoming traffic of a hostname. It provides an organized and effective way of spreading the inbound network or application traffic across multiple servers.

by Pascal

Content Delivery Network (CDN) is great and beneficial. In present days the need for fast and reliable access to any type of content is crucial. That is why it is more important than ever to understand what actually stands behind it. So, let’s take a minute to explain a little bit more about it. 

Content Delivery Network (CDN) explained.

Content Delivery Network (CDN) is a complex solution that focuses on delivering content to clients quickly by applying routing and cache mechanisms. The servers are positioned in very precise locations and cover a wide geographical area. They cache the data (code, videos, images), and the aim is to be as closer as possible to potential visitors. As a result, the clients receive reliable, fast service. In addition, CDN acts as a load balancing mechanism that is going to reduce the pressure on the primary server.
