If you want to forward a domain address that you have to a different domain or subdomain, a good way to do this would be to use a CNAME record. By setting up such a record, the domain name being redirected loses all of its records (A, MX, and so on) and instead, it takes the A record of the domain address it's pointed to. This way, if you are using a web design service by some provider that gives you a subdomain, you can use an actual domain and not only will it be forwarded to the website 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 point all the traffic from different subdomains to their main domain name, or to use the webmail service of your hosting provider by using webmail.your-doman.com, for instance. The latter will work only by setting up a CNAME record for a subdomain because such a record created for the main domain address renders it impossible to use e-mail addresses.
