The hosted domains feature of a website hosting account indicates the number of registered domain names that one could include in the same account. Registering a domain address and hosting it are 2 completely different services although many people consider them to be the same thing. While the registration means you become the owner of a specific domain name, the hosting element is what really enables you to have a website as this is where your files and e-mails are going to be. Because these are two different services, you are able to register a new domain with one company and host it with another one by modifying its name servers (DNS) - the domain address will work in the exact same way as if it was registered and hosted with the same company. Also, it is very important to know that changing the hosting means pointing the domain to an alternative company and not transferring it.
