The hosted domains feature of a hosting account denotes the number of registered domains that one could add within the same account. Registering a domain address and hosting it are two completely different services although many people consider them to be the exact same thing. While the registration signifies that you become the owner of a certain domain, the hosting aspect is what in fact permits you to have a website considering that this is where your files and e-mails will be. Because these are 2 separate services, it is possible to register a new domain name with one company and host it with another one 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. It is also very important to know that changing the hosting means pointing the domain address to an alternative company and not transferring it.
