Registering a domain name and hosting one is sometimes mistaken by a lot of people to be one and the same thing. They are in fact two separate services - the domain address registration is the actual name and nothing else, while the hosted domains feature refers to the number of already registered domain addresses that you can accommodate in the same hosting account and have site data and e-mails for them. Your sites will function in precisely the same way no matter whether the domain names are registered and hosted in one place or are registered with company A and pointed to company B. Simply registering a domain address without hosting it will grant you ownership, but will not allow you to have a website until you host this domain in some account so that records for it are set up and it starts opening the content from that account.
