If you wish to point a domain that you have to another domain or subdomain, a good way to do that would be to use a CNAME record. By setting up such a record, the domain address being forwarded loses all of its records (A, MX, and so forth) and instead, it takes the A record of the domain name 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 and not only will it be forwarded to the Internet site that you've set up, but it will also be displayed in the web browser address bar at all times. Some other possible uses of a CNAME record are to forward all of the traffic from different subdomains to their main domain name, or to use the webmail service of your hosting company by using webmail.your-doman.com, for instance. The latter will work only by creating a CNAME record for a subdomain because this type of a record created for the main domain address makes it impossible to use e-mail addresses.
