If you'd like to point a domain address that you have to some other domain name or subdomain, a good way to do that would be to use a CNAME record. By creating such a record, the domain address being redirected loses all its records (A, MX, and so on) and instead, it takes the A record of the domain name it is directed to. This way, if you are using 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 which you have created, but it will also be displayed in the browser address bar at all times. Some other possible uses of a CNAME record are to direct all the traffic from different subdomains to their main 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 due to the fact that such a record set up for the main domain address makes it impossible to use email addresses.
