If you wish to point a domain name that you have to a different domain name or subdomain, the best way to do that would be to use a CNAME record. By setting up such a record, the domain name being pointed loses all of its records (A, MX, and so forth) and instead, it takes the A record of the Internet domain it is pointed 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 pointed to the website which you have set up, but it will also be displayed in the Internet browser address bar at all times. Alternative possible uses of a CNAME record are to forward all of the visitors from various subdomains to their main 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 because this kind of a record created for the main domain name renders it impossible to use e-mail addresses.
