The hosted domains feature of a website hosting account indicates the amount of registered domains that you could add within the same account. Registering a domain address and hosting it are two different services even though many people consider them to be the very same thing. While the registration means that you become the owner of a specific domain address, the hosting part is what actually permits you to have a website as this is where your data and emails will be. Because these are two separate services, it is possible to register a new domain name with one company and host it with another by modifying its name servers (DNS) - the domain name shall work in the exact same way as if it was registered and hosted with the same company. It is also extremely important to know that changing the hosting means directing the domain address to a different company and not transferring it.
