If you want to direct a domain address that you have to a different domain or subdomain, a good way to do this would be to use a CNAME record. By creating such a record, the domain name being redirected loses all its records (A, MX, and so on) and instead, it takes the A record of the domain address it's 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 name and not only will it be redirected to the Internet site which you have created, but it'll also be displayed in the browser address bar at all times. Some other possible uses of a CNAME record are to forward all the visitors from various subdomains to their main domain name, or to use the webmail service of your hosting provider by using webmail.your-doman.com, for instance. The latter will work only by setting up a CNAME record for a subdomain since such a record set up for the main domain name renders it impossible to use e-mail addresses.
