Demystifying DNS: Everything You Need to Know About it in 2021

Demystifying DNS: Everything You Need to Know About Domain Name Systems for Ecommerce:

When you create an online store, you will quickly learn how to set up and manage your Demystifying DNS record, otherwise, your website will not have a custom domain name and URL. While most e-commerce platforms simplify this process, the instructions won’t teach you what a DNA record actually is. What exactly are you setting up? This message will shed light on the ‘what’ and ‘why’ behind DNA so that we can approach this important activity with full context from the start.

What is Demystifying DNA?

DNS stands for Domain Name System. Its main purpose is to map and redirect domain names to specific places on the web, such as your store. Every device connected to the internet has a unique IP address – you can find the IP address here. IP addresses are an important way for web browsers to find, load, and communicate with your website.

Since long lists of numbers in IP addresses are not friendly to human memory, we use domain names ( to easily find and access our favorite sites. Demystifying DNS is the system that translates domain names to their IP addresses so that web browsers can map and manage the website.

At its most basic level, DNA can be compared to the phone’s “Contacts” list. Instead of having to remember the contact’s phone number, you can simply select a name in Contacts and the phone will automatically dial the corresponding number. Again, there is a translation between the type of human memory (a name) and the necessary unique identifier (a phone number).

In addition to assigning a domain name, Demystifying DNA can also be used for various mapping functions, such as redirecting traffic to a subdomain or sending emails through a specific server.

5 types of Demystifying DNS records

While there are ten common types of Demystifying DNA records, there are only five that you will use in an online store or another website.


A name server stores and organizes individual Demystifying DNS records and is essential for linking a website’s URL to its underlying IP address. This makes it one of the most common ways to associate your domain name with your online store.

Most e-commerce platforms, including Volusion, do not require you to transfer your domain name to the platform you are using. Instead, you can contact your current domain registrar and get help redirecting your domain name to the platform name server.

Once the request is made, it can take about 24-72 hours for the Demystifying DNA changes to fully propagate across the internet; different parts of the world can also change at different times. An easy way to verify changes is to type the domain name into your browser’s address bar (use an incognito window if connected to your store). If the URL entered takes you to your store, the changes have been made.

CNAME record

A CNAME record is often used to create a subdomain of your main site. For example, if your main site is, you can create a subdomain called by adding a CNAME record of “store”.

Subdomains have SEO implications because search engines can crawl them independently of the main URL, but this isn’t always a bad thing – many companies use subdomains to provide the knowledge base, team resources, and other content that they want to separate from the main structure. site organization. Parent companies with multiple separate brands can also use brand subdomains.

CNAME records

While CNAME records can point to a hostname or URL, an A record can only indicate a static numeric IP address. Because platforms like Volusion don’t use static IP addresses, the IP address associated with your store may change from time to time. That’s why we recommend using A records to create subdomains or point to your own domain. If your store’s IP address changes, the A record will still be displayed for the old version, making your store temporarily unreachable without notice.

MX record

MX files, short for “mail exchanger”, are responsible for determining which email server will accept emails for your particular domain. If you list your name servers on a trading platform like Volusion, the default MX email servers will be listed in the MX records. (If you are using Volusion and prefer to use a third party like Gmail to host your specific domain)

SPF registration

Your store sends a series of automated messages to you and your customers, including password resets and confirmation emails. If you find that sending or receiving these emails has stopped, you can solve the situation by adding an SPF file. SPF files, abbreviated as “Sender Policy Framework”, are used to authorize external clients as trusted sources to send an email from your email address. You can add an SPF record to let your email provider know who can and cannot send your email address.


With that, you learned the principles of Demystifying DNA. While the basics may seem redundant if your store can streamline the process, you can make the right choice at the right time, with all the context. Approach your corporate store with a willingness to develop your understanding from the bottom up and the results will be rewarded with a well-functioning website, satisfied customers, and increased sales.
