The hosted domains feature of a website hosting account refers to the amount of registered domains that one could include in the very same account. Registering a domain name and hosting it are two completely different services although many people consider them to be the same thing. While the registration means you become the owner of a specific domain, the hosting part is what really enables you to have a web site because this is where your data and emails will be. Since these are two separate services, you are able to register a new domain address with one company and host it with another one by modifying its name servers (DNS) - the domain name will 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 directing the domain name to an alternative company and not transferring it.
