If you want to make a website, you need two things - a domain and a hosting plan for it. The domain registration is the actual web address which you enter in a browser to reach a site, while the hosting space is where your website data will be. These are 2 closely related, yet separate services, even though many people think that registering the domain is enough. Much like the disk space and the monthly traffic features which a given website hosting plan offers, there are a certain number of registered domain names you can include as hosted which means that you can have the web content for them in some account even when the domains are actually registered using a different firm. In technical terms, it doesn't matter if a domain name is registered and hosted with the same company or is registered with one company and directed to another - in any case your sites will function the very same way.
