The hosted domains feature of a website hosting account denotes the number of registered domains which you can include within the exact same account. Registering a domain name and hosting it are 2 different services although many people consider them to be the same thing. While the registration signifies that you become the owner of a given domain, the hosting element is what really permits you to have a web site since this is where your data and emails will be. Since these are 2 separate 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 address will work in the exact same way as if it was registered and hosted with the same company. It is also extremely important to know that changing the hosting means pointing the domain address to another company and not transferring it.
