The hosted domains feature of a hosting account denotes the amount of registered domains which you can add in the very same account. Registering a domain and hosting it are two different services although some people consider them to be the exact same thing. While the registration means you become the owner of a specific domain, the hosting aspect is what actually enables you to have a web site because this is where your data and email messages are going to be. Because these are 2 separate services, you are able to register a new domain address with one company and host it with another one by changing its name servers (DNS) - the domain will work in the exact same way just as if it was registered and hosted with the same company. It is also important to know that changing the hosting means pointing the domain to an alternative company and not transferring it.
