The hosted domains feature of a hosting account denotes the number of registered domains which you could include within the very same account. Registering a domain name and hosting it are two different services although many people consider them to be the very same thing. While the registration means you become the owner of a specific domain address, the hosting aspect is what really allows you to have a website since this is where your data and email messages will be. Since these are 2 separate services, you are able to register a new domain name with one company and host it with another by modifying its name servers (DNS) - the domain address shall work in the exact same way just as if it was registered and hosted with the same company. Also, it is important to know that changing the hosting means directing the domain address to a different company and not transferring it.
