If you'd like to forward a domain name that you have to another domain or subdomain, one way to do this 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 on) and instead, it takes the A record of the domain address it's forwarded 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 directed to the site that you have created, but it'll also appear in the Internet browser address bar at all times. Alternative possible uses of a CNAME record are to forward all of the targeted traffic from different subdomains to their main domain name, or to use the webmail service of your hosting company by using webmail.your-doman.com, for instance. The latter will work only by setting up a CNAME record for a subdomain since this kind of a record set up for the main domain makes it impossible to use e-mail addresses.
