If you'd like to forward a domain address that you have to another domain name or subdomain, the best way to do this would be to use a CNAME record. By setting up such a record, the domain being pointed loses all of its records (A, MX, and so forth) and instead, it takes the A record of the domain address 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 and not only will it be forwarded to the website that you have set up, but it will also appear in the web browser address bar at all times. 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 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 such a record created for the main domain address makes it impossible to use e-mail addresses.
