The hosted domains feature of a website hosting account refers to the number of registered domains that one could add within the very same account. Registering a domain and hosting it are two completely different services although many people consider them to be the very same thing. While the registration ensures that you become the owner of a specific domain address, the hosting aspect is what really permits you to have a web site since this is where your files and e-mails are going to be. As these are 2 different services, you are able to register a new domain name with one company and host it with another by modifying its name servers (DNS) - the domain name will work in the exact same way just as if it was registered and hosted with the exact same company. It is also important to know that changing the hosting means pointing the domain to another company and not transferring it.
