If you wish to create a web site, you need 2 things - a domain name and a hosting plan for it. The domain registration is the actual web address which you enter in an Internet browser to reach a website, while the hosting space is where your website files will be. These are 2 very closely connected, yet separate services, while many people think that registering the domain name is enough. Very similar to the disk space and the monthly traffic features which a given hosting plan features, there are a certain number of registered domain names you can add as hosted which means that you can have the web content for them in some account even when the domains have been registered using a different company. In technical terms, it doesn't matter if a domain is registered and hosted with the same company or is registered with one company and directed to another - in any case your sites will operate exactly the same way.
