If you would like to forward a domain name 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, and so forth) and instead, it takes the A record of the domain name it's pointed to. This way, if you use a web design service by some company that gives you a subdomain, you can use an actual domain and not only will it be directed to the site you have created, but it'll also appear in the web browser address bar at all times. Some other possible uses of a CNAME record are to point all of the targeted traffic from different subdomains to their main domain address, or to use the webmail service of your hosting provider by using webmail.your-doman.com, for instance. The latter will work only by creating a CNAME record for a subdomain because this kind of a record set up for the main domain address renders it impossible to use email addresses.
