If you'd like to direct a domain name that you have to another domain address 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 of its records (A, MX, and so on) and instead, it takes the A record of the domain name it's forwarded to. This way, if you use a web design service by some provider that gives you a subdomain, you can use an actual domain name and not only will it be pointed to the Internet site which you have created, but it'll also appear in the web browser address bar at all times. Alternative possible uses of a CNAME record are to forward all the traffic from different subdomains to their main Internet domain, or to use the webmail service of your hosting provider by using webmail.your-doman.com, for instance. The latter will work only by creating a CNAME record for a subdomain due to the fact that such a record created for the main domain address makes it impossible to use e-mail addresses.
