If you'd like to forward a domain address that you have to another domain name or subdomain, one way to do this would be to use a CNAME record. By setting up such a record, the domain being pointed loses all its records (A, MX, and so on) and instead, it takes the A record of the domain it is directed to. This way, if you are using 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 redirected to the website you have set up, but it will also appear in the browser address bar at all times. Alternative possible uses of a CNAME record are to redirect all of the visitors from different subdomains to their main Internet domain, 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 due to the fact that such a record created for the main domain name renders it impossible to use e-mail addresses.
