If you'd like to forward a domain name that you have to a different 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 name being redirected loses all of its records (A, MX, and so forth) and instead, it takes the A record of the domain name it's directed to. In this way, if you are using a web design service by some company that gives you a subdomain, you can use an actual domain name and not only will it be pointed to the website that you have set up, 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 visitors from various subdomains to their main Internet 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 simply because this type of a record set up for the main domain name renders it impossible to use e-mail addresses.
