The hosted domains feature of a web hosting account indicates the number of registered domain names that you could add within the exact same account. Registering a domain address and hosting it are 2 different services although some people consider them to be the same thing. While the registration means that you become the owner of a specific domain name, the hosting element is what really enables you to have a web site considering that this is where your data and e-mails are going to be. Since these are 2 separate services, it is possible to register a new domain name with one company and host it with another by changing its name servers (DNS) - the domain shall work in the exact same way just as if it was registered and hosted with the same company. Additionally, it is important to know that changing the hosting means directing the domain to a different company and not transferring it.
