Subdomain
On CPanel based systems, a subdomain is a method to map a hostname/url to a sub-directory. Example usage:
- Assume your domain is myhosteddomain.co.uk
- You install a forum into a directory in your webspace called /forum/
you can now access the forum as myhosteddomain.co.uk/forum/
- You can turn the directory "forum" into a sub-domain from within your Control Panel
Now you can also access your forum as forum.myhosteddomain.co.uk
Parked Domain
A parked domain is simply another domain which you can use to access the
SAME content as another domain. Example Usage:
- You have two domains myhosteddomain.co.uk and myhosteddomain.biz
- myhosteddomain.co.uk is the main domain for your website and you also want people to be able to access the site as myhosteddomain.biz, and have them both show the same content.
- You can add the "parked" domain from within your Control Panel
Now when someone uses either myhosteddomain.co.uk or myhosteddomain.biz they will go to the same website.
Add-On Domains
An add-on domain is a combination of the parked and subdomains, and allows you to host an additional domain within your account, but with
SEPARATE content. Example Usage:
- You have two domains myhosteddomain.co.uk and myhosteddomain.biz
- myhosteddomain.co.uk is the main domain for your website and you want people to be able to access a *different* site as myhosteddomain.biz
- You upload your additional website into a directory in your webspace called /site2/
you can now access the 2nd site as myhosteddomain.co.uk/site2/
- You can add the additional domain as an "add-on" from within your Control Panel, redirecting it to the site2 folder.
Now when someone types myhosteddomain.co.uk they get the original site and when they browse to myhosteddomain.biz they will go to the site2 website.
