Registering a domain name and hosting one is commonly mistaken by many people to be one and the same thing. These are in fact 2 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 names you can accommodate within the same website hosting account and have website data and e-mails for them. Your websites will function in precisely the same way regardless if the domain addresses 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 grant you ownership, but will not allow you to have a website unless you host this domain in some account so that records for it are created and it starts opening the information from that account.
