If you would like to direct a domain that you have to another domain name or subdomain, the best way to do that would be to use a CNAME record. By creating 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 forwarded to. By doing this, if you are using 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 directed to the Internet site that you have set up, but it will also be displayed in the Internet browser address bar at all times. Other possible uses of a CNAME record are to point all the traffic from various subdomains to their main Internet domain, or to use the webmail service of your hosting provider by using webmail.your-doman.com, for example. The latter will work only by setting up a CNAME record for a subdomain since this type of a record created for the main domain address makes it impossible to use e-mail addresses.
