Registering a domain and hosting one is sometimes mistaken by many people to be the same thing. These are in fact 2 separate services - the domain registration is the actual name and nothing more, while the hosted domains feature reveals the number of already registered domains which you can accommodate in the same website hosting account and have website data and email messages for them. Your websites will function in exactly the same way no matter if the domain addresses are registered and hosted at the same place or are registered with company A and directed to company B. Simply registering a domain address without hosting it will grant you ownership, but will not allow you to have a web site until you host this domain address in some account so that records for it are set up and it starts opening the information from that account.
