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