The hosted domains feature of a website hosting account denotes the amount of registered domain names which you can add in the exact same account. Registering a domain and hosting it are two completely different services although a lot of people consider them to be the exact same thing. While the registration signifies that you become the owner of a given domain, the hosting aspect is what in fact enables you to have a site because this is where your files and e-mails are going to be. Because these are two independent services, you are able to register a new domain name with one company and host it with another by modifying its name servers (DNS) - the domain address shall work in the exact same way as if it was registered and hosted using the same company. Also, it is important to know that changing the hosting means pointing the domain name to a different company and not transferring it.
