If you would like to forward a domain address that you have to another domain or subdomain, the best way to do this would be to use a CNAME record. By creating such a record, the domain address being forwarded loses all its records (A, MX, and so on) and instead, it takes the A record of the domain it is directed to. By doing this, 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 forwarded to the website 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 of the targeted traffic 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 creating a CNAME record for a subdomain due to the fact that this kind of a record created for the main domain address renders it impossible to use e-mail addresses.
