The hosted domains feature of a website hosting account denotes the number of registered domains that one could add in the same account. Registering a domain address and hosting it are two totally different services although some people consider them to be the same thing. While the registration signifies that you become the owner of a certain domain, the hosting element is what actually permits you to have a website as this is where your files and e-mails will be. Since these are two independent services, it is possible to register a new domain name with one company and host it with another one by changing its name servers (DNS) - the domain address will work in the exact same way just as if it was registered and hosted with the exact same company. Also, it is important to know that changing the hosting means directing the domain name to a different company and not transferring it.
