If you would like to direct a domain name that you have to some other domain address or subdomain, a good way to do this would be to use a CNAME record. By setting up such a record, the domain being redirected loses all of its records (A, MX, and so forth) and instead, it takes the A record of the domain it's directed to. In this way, if you use 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 set up, but it will also be displayed in the web browser address bar at all times. Some other possible uses of a CNAME record are to direct all of the traffic from different subdomains to their main domain address, or to use the webmail service of your webhosting company by using webmail.your-doman.com, for example. The latter will work only by setting up a CNAME record for a subdomain due to the fact that such a record set up for the main domain name renders it impossible to use e-mail addresses.
