The hosted domains feature of a website hosting account denotes the number of registered domains that one can include within the exact same account. Registering a domain and hosting it are 2 totally different services even though many people consider them to be the very same thing. While the registration ensures that you become the owner of a given domain address, the hosting aspect is what really enables you to have a website because this is where your data and email messages will be. Since these are 2 independent services, it is possible to register a new domain 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 exact same company. It's also extremely important to know that changing the hosting means directing the domain name to another company and not transferring it.
