If you want to direct a domain that you have to a different domain name or subdomain, one way 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 on) and instead, it takes the A record of the domain name it is directed to. By doing this, if you use a web design service by some provider that gives you a subdomain, you can use an actual domain and not only will it be redirected to the site that you have set up, but it will also be displayed in the Internet browser address bar at all times. Some other possible uses of a CNAME record are to direct all of the traffic from various subdomains to their main domain name, or to use the webmail service of your hosting company by using webmail.your-doman.com, for example. The latter will work only by creating a CNAME record for a subdomain simply because such a record set up for the main domain address makes it impossible to use e-mail addresses.
