What is a subdomain?

A subdomain is a subsection of a domain that operates as a separate site but is part of the primary or addon domain. Here are some key points about subdomains:

1. Structure: Subdomains are created as a prefix to the main domain, such as sub.domain.tld.
2. Independent Content: Each subdomain can host its content and files, separate from its domain's content.
3. Subdirectory: The files for a subdomain are stored in its document directory specified while creating a subdomain in a cPanel account.
4. Common Uses: Subdomains are often used for organizing content, creating development or staging sites, hosting blogs, forums, or e-commerce sections of a website (e.g., blog.domain.tld, shop.domain.tld).
5. DNS Configuration: Subdomains require DNS configuration, usually managed within cPanel depending on the domain's nameserver provider.
6. No Additional Costs: Creating subdomains does not incur additional costs, as they are part of the domain's hosting in a cPanel account.

Subdomains provide a way to segment your website's content while maintaining a unified domain structure.

Here are the steps to create a Subdomain in a cPanel:

1. Log into the cPanel account of your Shared/Reseller hosting service.
2. Click the "Domains" tool under the "Domains" section.
3. Click the "Create A New Domain" button.
4. Enter the subdomain name you would like to add in the "Domain" text box. (e.g., sub.domain.tld)
5. Deselect the "Share document root (/home/username/public_html) with 'domain.tld'." option. << This is the most important step; do not miss this part.
6. Enter the directory path where you would like the files to be stored/hosted for this domain. (It will autofill the default path as /home/username/sub.domain.tld)
7. Click the "Submit" button.
