If you wish to make a website, you need two things - a domain name and a web hosting plan for it. The domain registration is the actual web address which you type in an Internet browser to access a website, while the hosting space is where your site files will be. These are 2 closely related, but separate services, while many people assume that registering the domain is enough. Just like the disk space and the monthly traffic features that a given web hosting plan offers, there are a certain number of registered domain names you can add as hosted i.e. you can have the web content for them in some account even if the domains have been registered using a different firm. In technical terms, it doesn't matter whether a domain is registered and hosted with the same company or is registered with one company and pointed to another - either way your sites will function exactly the same way.
