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