If you would like to forward a domain address that you have to another domain name or subdomain, a good way to do this would be to use a CNAME record. By setting up such a record, the domain address being pointed loses all of its records (A, MX, and so on) and instead, it takes the A record of the Internet domain 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 and not only will it be redirected to the site that you have set up, but it'll also appear in the web 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 webhosting company by using webmail.your-doman.com, for example. The latter will work only by setting up a CNAME record for a subdomain because such a record created for the main domain name makes it impossible to use email addresses.
