In order to make a web site, you need two things - a domain and a website hosting plan for it. The domain registration is the actual web address that you type in a browser to reach a website, while the hosting space is where your site data will be. These are two very closely connected, yet independent services, while many people assume that registering the domain name is enough. Just like the disk space and the monthly traffic features that a given hosting plan features, there are a certain number of registered domains which you can include as hosted which means that you can have the web content for them in some account even when the domains have been registered through a different provider. In technical terms, it does not matter whether a domain is registered and hosted with the exact same company or is registered with one company and pointed to another - in any case your websites will function in exactly the same way.
