Understanding Recursive DNS server

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.

How can GeoDNS improve your performance?

What is GeoDNS?

You can find GeoDNS, also called global traffic director, or just traffic director. It is an effective approach for optimizing traffic to domains by implementing geographical-based routing. Additionally, it is considered a cloud alternative for load balancing. It has a positive effect on the performance of the network.

If you are running a business that distributes content all over the world, you could definitely benefit from it. GeoDNS provides you nameservers that are strategically positioned throughout the globe plus an efficient way to spread the traffic regarding queries’ locations.

DNS outage – Definition and what can cause it?

A DNS outage is a state of the Domain Name System in which you cannot access web pages with their domain name. Very unpleasant, right? In today’s article, we will look at what causes it and how you can protect yourself from it.

What is the definition of a DNS outage?

Domain Name System is the process that connects domain names to IP addresses. This is a necessary component of the Internet. It’s also one of the most precarious. DDoS and other hacker assaults on DNS servers have the potential to bring down large portions of the Internet. DNS issues are caused by more than just hackers. Hardware problems, database corruption, and networking issues can all cause DNS to go down.

Breaking down the process of DNS resolution

DNS resolution or domain resolution is the process of obtaining a domain name’s IP address. But how does it happen? Here you have a breakdown of the process of DNS resolution, explained step-by-step.

DNS resolution.

DNS resolution, or getting the IP address behind a domain name takes many steps. The DNS has a tree structure, with different levels that are responding queries for the zones (domains) that they keep. Each server that keeps the original data for a zone is called an authoritative DNS server, and it will have the most updated information about it. The other important part of the process is the DNS resolvers. They are DNS servers that search for answers and keep them based on the data’s TTL values.

Differences between Unicast DNS and Anycast DNS

Unicast DNS and Anycast DNS are both great ways to route the incoming traffic. Let’s see what are their differences!

Unicast DNS – Definition

Unicast DNS is a traffic routing mechanism that operates in a one-to-one way. The information is transferred from its source node to only one specific destination. The receives and the sender are the only participants in the particular communication in the selected route. Therefore, Unicast DNS is an impressive solution for the transportation of information on the Internet.

DNS load balancing – the best way to manage your traffic

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.

If you are an owner of a very popular website, suddenly you would notice that the traffic is going to be a lot. It is going to receive many numerous requests from customers and users. For each of these requests, it is going to be necessary to return a fast and accurate answer with the exact piece of data, such as video, text, and images. In addition, the whole process must be completed in a secure and reliable way.

Content Delivery Network (CDN) – beginner’s guide

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.
