The hosted domains feature of a website hosting account refers to the number of registered domain names that one could add within the exact same account. Registering a domain name and hosting it are 2 completely different services even though many people consider them to be the same thing. While the registration means you become the owner of a specific domain name, the hosting aspect is what in fact enables you to have a website considering that this is where your files and email messages will be. As these are 2 independent services, you are able to register a new domain name 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 with the same company. It is also very important to know that changing the hosting means pointing the domain name to another company and not transferring it.
