The hosted domains feature of a web hosting account refers to the amount of registered domains which you could add within the exact same account. Registering a domain name and hosting it are 2 completely different services although many people consider them to be the same thing. While the registration signifies that you become the owner of a specific domain, the hosting aspect is what actually allows you to have a website because this is where your data and e-mails are going to be. Since these are two different services, you'll be able to register a new domain address 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 with the exact same company. Additionally, it is very important to know that changing the hosting means directing the domain address to another company and not transferring it.
