A subdomain is a domain within another domain, to make things clearer I’ll give you one example!
Notice that the end part has ilove-pink.info which is the main domain.
You can also have this when cPanel is accessible for your hosting plan.
How can I create a subdomain?
First thing you do is sign in your cPanel account, and then look for the Subdomains icon.
Next, click this icon and it takes to another page.
Simply type in the desired subdomain in the blank field at the left side of where you see your domain name
*Automatically the designated document root is created as well, but you can also change this.
This is where the subdomain’s files are found.
After typing in your desired subdomain name, hit Create and then your done!
Now, the next thing you should know is how to
create an ftp account for a subdomain which is essential for your subhostees to be able to access their files.
