DNS (Domain Name System) is a very essential part of Internet System. It simply maps a FQDN (Full Qualified Domain Name), which is in human readable form. For example, www.tutorialspoint.com to IP address, which are used by computer machine, e.g. 117.18.237.191. For this process, DNS uses zone files that are stored in servers, which contains resource records to map a domain name to an IP address.

In this Simple Zone Editor, we can add two types of records −

Add an A Record

The A types of resource records are Host Name records. They contain the IP address of a specific host, and maps the Domain Name with 32-bit IP address.

To add an A type record, perform the following steps −

Step 1 − Open the Editor by clicking Simple Zone Editor found in Domains Section of cPanel Home.

Step 2 − Find Add an A Record in the Simple Zone Editor interface.

Step 3 − Enter Name in Name textbox and IP address in Address textbox.

Step 4 − Press Add an A Record. If successful, you will get a success message.

Note − ‘A’ records are essential for accessing your website. They allow DNS servers to locate your website and its services. Without an ‘A’ record, visitors can’t access your website. The cPanel automatically configures A type records for your domain and website, as soon as they are created.

Add a CNAME Record

The CNAME records are used to add an Alias to its associated domain name. You can point multiple CNAME records to a single A record. So that when the DNS looks up for the Alias, you can simply rename a host, which is defined in the A records.

To add a CNAME record, please follow these steps.

Step 1 − Scroll down on Simple Zone Editor to find Add a CNAME Record.

Step 2 − Enter the desired Alias name for CNAME record on Name textbox and Enter a FQDN in CNAME textbox to which you want your Alias pointing to.

Step 3 − Click Add CNAME Record and you should see a success message.

Remove an A or CNAME Record

To remove a user defined A or CNAME Record, please scroll below on Simple Zone Editor to find User–Defined Records. Press the Delete link corresponding to the Record you want to remove.

You should see a success message when record is deleted.

 

Subdomain is a domain, which is a part of a primary domain and exists in the same server. We can also say it is a second website, which resides under the main domain, however it may or may not have any relation with the root website. we can run a new website under this subdomain.

For Example − The domain.com is a subdomain for the root domain tutorialspoint.com and blog.tutorialpoint.com can also be accessed by tutorialpoint.com/blog.

To Create a Subdomain

Step 1 − Click Subdomains, which can be found under Domains section.

Step 2 − Enter the Subdomain text you want to create. Select the root Domain for your subdomain and the Document Root will be automatically filled according to your Subdomain. You may leave it as it is or you may change it according to your need. Click Create button to create your Subdomain.

If your subdomain is created successfully, then you will see a Success message like the one shown below.

Managing Redirection

If you want your subdomain to point to another domain rather than loading content from your own server, you can do so by clicking Manage Redirection as shown below.

You will be taken to the screen, where you can manage redirection for your subdomain. Enter the new URL, where you want to redirect your subdomain to. Click save and your redirection will be saved successfully. If you want to disable the redirection later on, you may click Disable Redirection.
