The hosted domains feature of a website hosting account denotes the number of registered domains that you could include in the very same account. Registering a domain and hosting it are two different services although many people consider them to be the exact same thing. While the registration signifies that you become the owner of a certain domain address, the hosting aspect is what really permits you to have a site as this is where your data and email messages are going to be. Since these are two separate services, you can register a new domain with one company and host it with another one by modifying its name servers (DNS) - the domain is going to 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.
