Registering a domain name and hosting one is frequently mistaken by many people to be one and the same thing. These are in reality two separate services - the domain name registration is the actual name and nothing more, while the hosted domains feature refers to the number of already registered domain names that you can accommodate within the same hosting account and have site files and e-mails for them. Your websites will work in exactly the same way regardless if 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 grant you ownership, but will not enable you to have a web site unless you host this domain address in some account so that records for it are created and it starts opening the information from that account.
