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.

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.

Why should you choose Anycast DNS?

Anycast DNS explained

Anycast DNS is a traffic routing mechanism that delivers content fast from websites. It uses multiple nameservers that hold one individual IP address. 

Every one of the servers is located in a separate geographical location in order to be as close as possible to the users. The reason for that is to achieve a faster response to the request, which leads to a better user experience. The server that is nearest and available to the client requesting the website is going to answer. Any possibilities for latency are reduced to a minimum. Your website is easily reachable, and customers won’t wait long to connect with it.

Additionally, if the nearest server it’s not working due to maintenance, for example, another server, the next closest, is going to answer.
