The hosted domains feature of a website hosting account refers to the amount of registered domains which you could add in the same account. Registering a domain and hosting it are 2 totally different services although a lot of people consider them to be the very same thing. While the registration ensures that you become the owner of a given domain, the hosting element is what in fact enables you to have a web site considering that this is where your files and email messages will be. Since these are two different services, you are able to register a new domain address with one company and host it with another one by modifying its name servers (DNS) - the domain shall work in the exact same way as if it was registered and hosted using the same company. Also, it is very important to know that changing the hosting means pointing the domain address to an alternative company and not transferring it.
