The hosted domains feature of a hosting account denotes the amount of registered domain names that one can add in the very 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 means that you become the owner of a given domain, the hosting aspect is what really permits you to have a site as this is where your data and e-mails will be. Because these are two separate services, you can register a new domain address with one company and host it with another by modifying its name servers (DNS) - the domain address shall work in the exact same way just as if it was registered and hosted with the same company. Also, it is very important to know that changing the hosting means pointing the domain name to an alternative company and not transferring it.
