A subdomain is a second website, with its own unique content, but there is no new domain name. Instead, you use an existing domain name and change the www to another name. The subdomain name looks like forums.domain.com, help.domain.com, help2.domain.com.
- Log into your cPanel and click the "Subdomains" link under the Domains section.
- On the next page enter the name of the subdomain you wish to add and select the domain in the drop down box. If you wish the document root to be different you can enter a different path in the box below.
- Click the create button.
