If you want to forward a domain address that you have to another domain or subdomain, one of the ways to do this would be to use a CNAME record. By setting up such a record, the domain name being redirected loses all its records (A, MX, and so on) and instead, it takes the A record of the domain it is directed to. In 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 redirected to the Internet site you have set up, but it will also be displayed in the Internet browser address bar at all times. Some other possible uses of a CNAME record are to forward all of the visitors from various subdomains to their main domain address, or to use the webmail service of your webhosting 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 such a record created for the main domain address makes it impossible to use e-mail addresses.
