The hosted domains feature of a website hosting account indicates the number of registered domains that one can add within the very same account. Registering a domain and hosting it are two different services even though many people consider them to be the same thing. While the registration signifies that you become the owner of a specific domain address, the hosting element is what in fact allows you to have a site because this is where your data and email messages will be. Since these are two separate services, you can register a new domain address with one company and host it with another one by changing its name servers (DNS) - the domain name shall work in the exact same way just as if it was registered and hosted using the same company. Additionally, it is extremely important to know that changing the hosting means directing the domain to a different company and not transferring it.
