The hosted domains feature of a web hosting account indicates the number of registered domain names that one could include within the same account. Registering a domain and hosting it are two totally different services although some people consider them to be the exact same thing. While the registration means you become the owner of a given domain name, the hosting aspect is what actually enables you to have a website considering that this is where your files and emails are going to be. Since these are two independent services, you are able to register a new domain name 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 name to another company and not transferring it.
