I still get confused about the differences between sub domains, parked domains and add-on domains… so here’s a handy reference definition: 

Sub domain 

  • Lets say your domain is mysite.co.uk
  • You install a Discusssion Forum and put in in a directory called mysite.co.uk/forum/
  • You can turn the forum into a sub-domain by adding it as a sub-domain from your Control Panel
  • Now you can access your forum as either mysite.co.uk/forum OR forum.mysite.co.uk
  • This generally costs you nothing and is free.

Parked Domain

  • You have two domains mysite.co.uk and my-other-site.co.uk
  • mysite.co.uk is the domain of your website and you want to add my-other-site.co.uk
  • You want them both to go to the same place. In other words, when someone types either www.mysite.co.uk or www.my-other-site.co.uk they will go to the same page(s) on your website.
  • In order to have additional parked domains you need to purchase them from a registry.

Add-On Domains

  • You have two domains mysite.co.uk and my-other-site.co.uk
  • You want the two domains to be totally separate/independent websites
  • In order to have additional add-on domains you need to purchase them from a registry.
