The hosted domains feature of a website hosting account indicates the number of registered domain names that one could add in the same account. Registering a domain address and hosting it are two different services although some people consider them to be the very same thing. While the registration signifies that you become the owner of a specific domain address, the hosting aspect is what really allows you to have a site since this is where your files and email messages are going to be. Because 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 address will work in the exact same way just as if it was registered and hosted with the same company. It's also extremely important to know that changing the hosting means directing the domain name to another company and not transferring it.
