A Weebly site can not only be used with your root custom domain web site address, it can also be used as a sub-domain of your custom domain. This is best illustrated with an example. Your domain can be registered through one registrar and hosted at a different hosting provider. Similarly, different sub-domains can be hosted at different places.
- weeblyforums.com is registered with GoDaddy.
- The root domain weeblyforums.com is hosted at HostGator.
- The sub-domain demo.weeblyforums.com is hosted at Weebly. (Ex: http://demo.weeblyforums.com/89JNM)
