If you would like to forward a domain address that you have to a different domain name or subdomain, a good way to do that would be to use a CNAME record. By creating such a record, the domain name being forwarded loses all of its records (A, MX, and so forth) and instead, it takes the A record of the Internet domain it's directed to. 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 forwarded to the website which you have created, but it'll also appear 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 Internet 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 setting up a CNAME record for a subdomain simply because this kind of a record created for the main domain makes it impossible to use e-mail addresses.
