The hosted domains feature of a web hosting account denotes the number of registered domains that one can add in the same account. Registering a domain address and hosting it are two totally different services even though many people consider them to be the very same thing. While the registration ensures that you become the owner of a specific domain, the hosting aspect is what in fact permits you to have a website as this is where your data and email messages are going to be. Because these are two separate services, you can register a new domain with one company and host it with another by changing its name servers (DNS) - the domain 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 directing the domain to another company and not transferring it.
