If you would like to forward a domain name that you have to some other domain name or subdomain, one of the ways 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 domain name it's redirected to. This way, if you are using a web design service by some provider that gives you a subdomain, you can use an actual domain and not only will it be forwarded to the Internet site that you've set up, but it'll also appear in the Internet browser address bar at all times. Some other possible uses of a CNAME record are to redirect all of the traffic from different subdomains to their main domain, or to use the webmail service of your webhosting 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 such a record set up for the main domain address renders it impossible to use e-mail addresses.
