If you'd like to point a domain that you have to another domain address or subdomain, the best way to do this would be to use a CNAME record. By setting up such a record, the domain address being forwarded loses all its records (A, MX, and so forth) and instead, it takes the A record of the Internet domain it is directed to. In this way, 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 forwarded to the Internet site that you have created, but it will also be displayed in the Internet browser address bar at all times. Alternative possible uses of a CNAME record are to forward all of the traffic from various subdomains to their main domain address, or to use the webmail service of your hosting company by using webmail.your-doman.com, for example. The latter will work only by setting up a CNAME record for a subdomain since this kind of a record set up for the main domain name makes it impossible to use e-mail addresses.
