The hosted domains feature of a hosting account refers to the number of registered domain names that you could add within the same account. Registering a domain address and hosting it are two 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, the hosting aspect is what actually permits you to have a web site because this is where your data and emails will be. Since these are two independent services, you can register a new domain address with one company and host it with another by changing its name servers (DNS) - the domain will work in the exact same way as if it was registered and hosted with the same company. Additionally, it is extremely important to know that changing the hosting means pointing the domain name to another company and not transferring it.
