The hosted domains feature of a web hosting account indicates the amount of registered domain names which you can add within the same account. Registering a domain address and hosting it are two different services although some people consider them to be the exact same thing. While the registration means that you become the owner of a specific domain name, the hosting part is what really permits you to have a web site considering that this is where your data and email messages will be. Because these are 2 different services, you can register a new domain name with one company and host it with another by changing its name servers (DNS) - the domain is going to work in the exact same way as if it was registered and hosted with the exact same company. It is also extremely important to know that changing the hosting means pointing the domain to an alternative company and not transferring it.
