The hosted domains feature of a web hosting account indicates the number of registered domain names that one could add in the exact same account. Registering a domain and hosting it are 2 different services although some people consider them to be the exact same thing. While the registration means that you become the owner of a given domain address, the hosting aspect is what in fact enables you to have a site considering that this is where your files and e-mails are going to be. Since these are 2 different services, you'll be able to register a new domain with one company and host it with another one by changing 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. Also, it is very important to know that changing the hosting means directing the domain name to a different company and not transferring it.
