A Complete Guide To DNS Management: DNS Records Explained

Internet use is full of immense space in DNS, just like the web users’ address book can be used. DNS management is crucial for ensuring that your domain is registered to the correct IP address, making it possible for people to find your website or utilize your services quickly.

This knowledge base will take you through the management of DNS and help you understand what DNS records are and why they are essential.

Let’s get started!

Understanding DNS: The Backbone of the Internet

Knowing DNS is like learning the backbone of the internet. As the postal system does, so does DNS by converting user-friendly domain names into IP addresses understood by machines.

Such a translation process happens beneath the hood to provide users with a smooth experience when visiting websites, sending emails, and engaging in myriad other online activities. Without DNS, getting through the Internet would be like finding a specific location without a map or address. 

DNS management allows individuals and organizations to take control and customize their online presence, directing traffic to the appropriate servers and services.

In other words, DNS is what makes the functioning of the Internet possible and sustains its accessibility, which in turn shapes the digital environment that we come across throughout the day. Hence, DNS fundamentals are necessary for every person who wants to understand the operations of the internet and how to use it effectively.

DNS Records: The Building Blocks of DNS Management

DNS records are the fundamental components of DNS management, containing crucial information about your domain's configuration. Each record serves a specific purpose: directing traffic, handling emails, and more. Here are some common types of DNS records:

A Record (Address Record)

An A record links a domain name to an IP address, essentially pointing users to the website's correct server. It's like a signpost guiding traffic to the right destination.

CNAME Record (Canonical Name Record)

A CNAME record aliases one domain name to another. This is especially beneficial when you link many domain names to the same server or hosting provider. Consider establishing shortcuts for your domain.

MX Record (Mail Exchange Record)

MX records identify the mail server that receives email on behalf of your domain. This record guarantees that emails sent to your domain are correctly routed, which is critical for efficient email communication.

TXT Record (Text Record)

TXT records include extra information about your domain, such as SPF (Sender Policy Framework) records for email authentication. These documents contain critical security and verification mechanisms.

SRV Record (Service Record)

SRV records specify the location of your domain's services, such as VoIP and LDAP. They are important in allowing many cloud-based services to run properly.

DNS Management in Action: How It Works

Now that we understand the essential DNS records let's see how DNS management works. Suppose you want to host a website on a cloud server. Here's a simplified breakdown of the process:

Registering a Domain: You will be screened by a domain registrar, and the domain name will be registered.

Setting DNS Records: You enter your domain registrar's DNS management server and specify the relevant records. An A record generally, points to the cloud server IP address for hosting your website on the cloud.

Propagation: The next step is propagating the updated DNS record throughout the Internet, which may take about 48 hours. During process time, DNS servers everywhere update records.

Website Accessibility: With propagation done, users can simply type in your website's domain name on their browsers, and the DNS will then point them to the right cloud server where your website is hosted.
