If you wish to point a domain name that you have to some other domain address 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 its records (A, MX, and so on) and instead, it takes the A record of the domain address it is forwarded 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 pointed to the site that you've created, but it'll also appear in the web browser address bar at all times. Some other possible uses of a CNAME record are to point all the traffic from various subdomains to their main domain, 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 such a record created for the main domain makes it impossible to use e-mail addresses.
