Simplify your web addresses by creating sub-domains
You've created a website and want to add a second content area (forum, photo space, online shop)? Sub-domains let you add names to your existing domain name which enable users to quickly access certain parts of your website.
Make organising your site easier
Each sub-domain is associated with a folder that contains the required part of the site.
You can give access to password-protected parts of your website to authorised persons.
