In order to create a web site, you need 2 things - a domain name and a hosting plan for it. The domain registration is the actual website address that you enter in a browser to access a site, while the hosting space is where your website data is going to be. These are two very closely connected, but independent services, while many people think that registering the domain name is enough. Similar to the disk space and the monthly traffic features which a given hosting plan has, there are a certain number of registered domain names that you can include as hosted which means that you can have the web content for them in some account even if the domains are actually registered via a different firm. In technical terms, it does not matter whether a domain is registered and hosted with the same company or is registered with one company and directed to a different one - in any case your websites will function exactly the same way.
