The hosted domains feature of a website hosting account indicates the number of registered domain names that one could include within the exact same account. Registering a domain name and hosting it are 2 totally different services although some people consider them to be the exact same thing. While the registration ensures that you become the owner of a specific domain name, the hosting part is what in fact permits you to have a site since this is where your data and emails will be. Because these are 2 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 will work in the exact same way just as if it was registered and hosted with the same company. It's also important to know that changing the hosting means pointing the domain name to another company and not transferring it.
