If you wish to forward a domain address that you have to a different domain or subdomain, one of the ways to do that 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 address it is forwarded to. That way, if you use a web design service by some company that gives you a subdomain, you can use an actual domain name and not only will it be pointed to the Internet site you have created, but it will also appear in the browser address bar at all times. Some other possible uses of a CNAME record are to forward all the targeted traffic from different subdomains to their main domain address, or to use the webmail service of your hosting provider 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 type of a record set up for the main domain makes it impossible to use e-mail addresses.
