How do I create a subdomain?

A subdomain is a section that runs as an independent address under your main domain (blog.yoursite.com, support.yoursite.com, etc.). In cPanel you can add one in two ways: via the classic Subdomains tool or the new Domains screen. Both produce the same result; use whichever is more prominent in your cPanel version.

1. Adding via the Subdomains Tool (Classic Method)

1. Log in to cPanel.
2. In the top search box, type subdomains and click the result.
3. In the Subdomain field, enter only the prefix (e.g. blog).
4. Select your main domain from the Domain menu.
5. The Document Root field is automatically filled as public_html/blog. Leave the default unless you want to use a different folder.
6. Click the Create button.

2. Adding via the Domains Tool (New cPanel Interface)

In newer cPanel versions, Subdomains, Addon Domains and Aliases are unified into a single Domains screen. If you use this interface:

1. On the cPanel main screen, in the Domains section, click Domains.
2. Click Create A New Domain in the top right.
3. In the Domain field, enter the full subdomain address (e.g. blog.yoursite.com).
4. Make sure Share document root is off; otherwise the subdomain will point to your main site's folder.
5. Adjust the Document Root if needed (default public_html/blog.yoursite.com).
6. Click the Submit button.

3. Are DNS and SSL Automatic?

If your domain uses Kolan IT's nameservers, the required A record for the subdomain is created automatically; you don't need to do anything extra. The SSL certificate is then attached automatically by AutoSSL within 15 minutes to a few hours.

4. Deleting a Subdomain

• Classic interface: In the Subdomains tool, find the entry and click Remove in the Actions column.
• New Domains interface: In the Domains list, use Manage → Remove Domain next to the subdomain row.

Deletion only removes the subdomain record; the Document Root folder and its files are not deleted. If you also want to remove the content, manually delete the folder via File Manager.
