The hosted domains feature of a hosting account denotes the amount of registered domains that you could include within the exact same account. Registering a domain address and hosting it are two totally different services although some people consider them to be the exact same thing. While the registration ensures that you become the owner of a given domain address, the hosting element is what really enables you to have a web site considering that this is where your data and emails will be. Since these are 2 independent services, you can register a new domain with one company and host it with another by modifying its name servers (DNS) - the domain name will work in the exact same way as if it was registered and hosted using the same company. Additionally, it is important to know that changing the hosting means directing the domain to another company and not transferring it.
