If you would like to direct a domain address that you have to another domain address or subdomain, one way to do that would be to use a CNAME record. By creating such a record, the domain name being forwarded loses all its records (A, MX, and so forth) and instead, it takes the A record of the Internet domain it's forwarded to. By doing this, if you are using 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 redirected to the Internet site that you have 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 forward all of the targeted 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 instance. The latter will work only by setting up a CNAME record for a subdomain because this type of a record set up for the main domain address renders it impossible to use e-mail addresses.
