If you would like to forward a domain name that you have to a different domain or subdomain, one of the ways to do this would be to use a CNAME record. By setting up such a record, the domain address being pointed loses all its records (A, MX, and so forth) and instead, it takes the A record of the Internet domain it is redirected to. That 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 pointed to the Internet site that you have created, but it'll also appear 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 domain address, or to use the webmail service of your hosting provider by using webmail.your-doman.com, for example. The latter will work only by creating a CNAME record for a subdomain due to the fact that this kind of a record set up for the main domain makes it impossible to use email addresses.
