If you wish to direct a domain that you have to another domain address or subdomain, a good way to do that would be to use a CNAME record. By setting up such a record, the domain being pointed loses all of its records (A, MX, etc) and instead, it takes the A record of the Internet domain it's redirected to. By doing this, if you are using a web design service by some provider that gives you a subdomain, you can use an actual domain name and not only will it be pointed to the website that you've created, 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 redirect all of the visitors from various subdomains to their main domain, or to use the webmail service of your hosting company by using webmail.your-doman.com, for instance. The latter will work only by creating a CNAME record for a subdomain because such a record created for the main domain address makes it impossible to use e-mail addresses.
