If you'd like 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 creating such a record, the domain address being pointed loses all of its records (A, MX, etc) and instead, it takes the A record of the Internet domain it is forwarded 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 name and not only will it be forwarded to the Internet site that you have created, but it will also appear in the web browser address bar at all times. Some other possible uses of a CNAME record are to point all of the targeted 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 since this kind of a record created for the main domain renders it impossible to use email addresses.
