Registering a domain and hosting one is sometimes mistaken by many people to be one and the same thing. These are in fact two different services - the domain address registration is the actual name and nothing more, while the hosted domains feature reveals the number of already registered domain addresses that you can accommodate within the same web hosting account and have website data and email messages for them. Your sites will function in exactly the same way no matter whether the domains are registered and hosted in one place or are registered with company A and pointed to company B. Simply registering a domain name without hosting it will give you ownership, but will not enable you to have a website if you don't host this domain in some account so that records for it are created and it starts opening the information from that account.
