The hosted domains feature of a website hosting account indicates the amount of registered domains that you can include in the exact same account. Registering a domain name and hosting it are 2 completely different services although a lot of people consider them to be the same thing. While the registration means that you become the owner of a given domain address, the hosting element is what actually allows you to have a site as this is where your data and e-mails are going to be. Because these are two separate services, it is possible to register a new domain name with one company and host it with another 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 same company. Also, it is extremely important to know that changing the hosting means directing the domain name to an alternative company and not transferring it.
