DNS resolution process described in detail

DNS resolution process described in detail

DNS resolution process, generally defined, is a service that uses a domain to reach an IP address. Due to this system, we can access websites easily and quickly just by entering their domain. In our article, we will explain in detail this whole process. 

The definition of DNS resolution

As we have already said, Domain Name System (DNS) resolution is the process of obtaining an IP address through its domain. This is in order to facilitate online users. To visualize what DNS resolution is, we can most easily imagine a phone directory with people’s names. We don’t remember their phone numbers because it’s too difficult. The same principle is working for DNS resolution. Through the domain name, it reaches its IP address.

What does Round Robin DNS mean?

What does Round Robin DNS mean?

Round Robin DNS is a very effective traffic distribution method. In this article, we’ll look at its concept, its key benefits, and how to set it up. But first, let’s see what Load balancing is.

Load balancing – definition

Load balancing is an approach to improving network performance by distributing traffic among different servers using a specific algorithm. The visitor’s IP address, a server’s present occupation, a weighted loading balance based on the servers’ capacity, and other factors could be used to manage traffic.

Try Traceroute command for better understanding of your network

Try Traceroute command for better understanding of your network

The Traceroute command is a network utility that allows you to observe a query’s complete path. In this article, we will take a detailed look at it and why it is so beneficial to do it. 

Traceroute command – definition

The Traceroute command is a basic command-line program that displays each hop of a query from your machine to the destination – an IP address or a domain name. It calculates a probe’s route and returns the result.

The query will traverse the Internet, passing from one router to the next until it reaches its destination. Your computer will send packets to each hop and get responses to them. In this way, you’ll get data for each of the points along the trip, from your device to the destination.

Free DNS service: Who can benefit from it? 

Free DNS service: Who can benefit from it? 

Free DNS service is a tool provided by DNS hosting companies. We will find out what it is and who can take advantage of it in today’s article.

Why is DNS service important for your business?

The DNS service is fundamental for online users to visit your website.

DNS servers handle domain-related queries. Additionally, they have an impact on your website’s performance (privacy, speed, and uptime) as well as the customer experience.

It is necessary to have DNS service because:

Load balancing: How does it handle the traffic?

Load balancing: How does it handle the traffic?

DNS load balancing is a widely used technique for optimizing the management of a hostname’s incoming traffic. It is becoming an increasingly popular method. But, as we’ll see later in the text, there’s a reason for this.

What is load balancing meaning? 

Load balancing in DNS is a method of distributing client requests among server machines by configuring a domain. We can associate the domain with a website, a mail system, etc., or any other Internet-based service.

If you are the owner of a large and popular website, it means that you will have a lot of requests for it. In addition, it needs to be fast, provide up-to-date information and process the requests it receives accurately and quickly. This is where traffic balancing comes in.

A record vs AAAA record: What is the difference?

A record vs AAAA record: What is the difference?

A and AAAA records are among the most important in the DNS system. The process of resolving a domain name to find the IP address is managed by these two types of DNS records. This is what makes them valuable and essential to access the internet easily and quickly.  

What does A record mean? 

A record is the most popular and simple type used in DNS servers, where “A” stands for Address. The A record uses a domain name to find the device’s IP address connected to the Internet. 

Consider the following example – You are a web user and want to access www.abc123.com. This request is sent to the DNS resolver. It identifies the IP, and then the page automatically loads. 

In other words, the A record uses the domain name to find the IP address (IPv4 address). 

AAAA record – definition

Everything you have to know about CDN

Everything you have to know about CDN

We all are very related to CDN! Besides business people, we are all users, and from both sides, we interact daily with CDNs. Without them, the delivery of content wouldn’t be as efficient as it’s currently. A CDN is behind each character, each image pixel, and video frame of the content you daily offer and consume. 

Are you interested now? Great! Here you have everything you have to know about CDN.

What is a CDN?

A CDN or a content delivery network is a set of servers distributed in different geographical points for accelerating web content delivery. By covering those different points on the planet, servers bring that content closer to the users’ physical location.

​Anycast DNS vs. GeoDNS

​Anycast DNS vs. GeoDNS

Ok, so you are checking how to improve your DNS infrastructure. Great! There are different routing methods that you can use for your domain resolution. Now we will compare Anycast DNS and GeoDNS and see what their advantages and disadvantages are.

​What is Anycast DNS?

Anycast DNS is a simple routing method with a single IP address for all of the name servers. The servers are located in different international locations. That way, a client’s query will search for that single IP address, no matter from where in the world he or she connects, and it will reach the closest server.

Anycast DNS – Major improvement for your network.

Anycast DNS – Major improvement for your network.

Are you building or managing a network? Congrats! That is a titanic job, but also exciting, especially if it’s a large network. A lot of stuff must be considered for it to work properly. For instance, have you ever thought about how the massive amount of data packets is handled within a network? Well, this task is possible thanks to routing methods, like Anycast DNS.

What is Anycast DNS?

Anycast DNS is a method for networks to route and address data packets. When you use it, a destination IP address is shared by different servers (or other devices) in different locations. Like this, routers (recursive servers) direct data packets addressed to such a destination to the closest location to the source or sender.
