If you would like to direct a domain that you have to some other domain or subdomain, a good way to do that would be to use a CNAME record. By creating such a record, the domain being pointed loses all of its records (A, MX, and so on) and instead, it takes the A record of the Internet domain it is pointed to. In this way, if you use a web design service by some company that gives you a subdomain, you can use an actual domain name and not only will it be forwarded to the site that you have set up, but it'll also be displayed in the Internet browser address bar at all times. Other possible uses of a CNAME record are to direct all of the traffic from different subdomains to their main Internet domain, or to use the webmail service of your hosting company by using webmail.your-doman.com, for instance. The latter will work only by setting up a CNAME record for a subdomain simply because this type of a record created for the main domain name renders it impossible to use e-mail addresses.
