If you want to make a website, you need 2 things - a domain and a hosting plan for it. The domain registration is the actual website address that you type in a browser to access a website, while the hosting space is where your website data will be. These are two very closely connected, yet individual services, even though many people assume that registering the domain name is enough. Similar to the disk space and the monthly traffic features which a given web hosting plan has, 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 if the domains have been registered through a different company. In technical terms, it does not matter whether a domain name is registered and hosted using the same company or is registered with one company and pointed to a different one - in either case your websites will function in exactly the same way.
