The hosted domains feature of a website hosting account refers to the number of registered domains that you can add in the very same account. Registering a domain name and hosting it are two completely different services although some people consider them to be the same thing. While the registration signifies that you become the owner of a certain domain name, the hosting element is what actually enables you to have a web site as this is where your files and e-mails will be. Since these are two separate services, you are able to register a new domain name with one company and host it with another by changing its name servers (DNS) - the domain address is going to work in the exact same way just as if it was registered and hosted with the exact same company. Also, it is very important to know that changing the hosting means directing the domain address to another company and not transferring it.
