The hosted domains feature of a web hosting account denotes the number of registered domains which you could add in the exact same account. Registering a domain address and hosting it are 2 totally different services even though many people consider them to be the same thing. While the registration means you become the owner of a given domain name, the hosting aspect is what in fact enables you to have a web site as this is where your data and e-mails will be. Since these are two different services, you are able to register a new domain with one company and host it with another by modifying its name servers (DNS) - the domain shall work in the exact same way just as if it was registered and hosted with the exact same company. It is also very important to know that changing the hosting means pointing the domain address to a different company and not transferring it.
