If you'd like to direct a domain that you have to a different domain or subdomain, one way to do this would be to use a CNAME record. By setting up such a record, the domain being redirected 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 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 created, but it'll also be displayed in the browser address bar at all times. Other possible uses of a CNAME record are to point all of the targeted traffic from various subdomains to their main domain name, 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 because such a record created for the main domain address makes it impossible to use email addresses.
