If you want to forward a domain that you have to another domain or subdomain, a good way to do that would be to use a CNAME record. By creating 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 it's pointed to. In this way, 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 pointed to the Internet site that you've set up, but it'll also be displayed in the browser address bar at all times. Some other possible uses of a CNAME record are to redirect all of the traffic from different subdomains to their main domain address, 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 type of a record set up for the main domain name renders it impossible to use e-mail addresses.
