The hosted domains feature of a web hosting account refers to the amount of registered domain names that one could add within the exact same account. Registering a domain and hosting it are two different services although a lot of people consider them to be the very same thing. While the registration ensures that you become the owner of a given domain, the hosting aspect is what actually enables you to have a site considering that this is where your data and e-mails are going to be. Because these are 2 independent services, it is possible to register a new domain name with one company and host it with another by changing its name servers (DNS) - the domain address shall work in the exact same way as if it was registered and hosted with the same company. Also, it is very important to know that changing the hosting means directing the domain address to an alternative company and not transferring it.
