Registering a domain and hosting one is sometimes mistaken by many people to be the same thing. These are in reality 2 separate services - the domain name registration is the actual name and nothing more, while the hosted domains feature refers to the amount of already registered domains that one could accommodate in the same website hosting account and have site data and e-mails for them. Your websites will function in exactly the same way no matter whether the domains are registered and hosted at the same place or are registered with company A and pointed to company B. Simply registering a domain address without hosting it will give you ownership, but will not enable you to have a website unless you host this domain address in some account so that records for it are created and it starts opening the content from that account.
