The hosted domains feature of a web hosting account denotes the amount of registered domains that you could include in the same account. Registering a domain address and hosting it are 2 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 specific domain address, the hosting element is what in fact enables you to have a website because this is where your data and e-mails are going to be. As these are 2 separate services, you are able to register a new domain address with one company and host it with another one by changing its name servers (DNS) - the domain name will work in the exact same way just as if it was registered and hosted using the same company. It's also important to know that changing the hosting means directing the domain name to an alternative company and not transferring it.
