If you want to forward a domain that you have to a different domain or subdomain, one way to do that would be to use a CNAME record. By setting up such a record, the domain being forwarded loses all of its records (A, MX, and so forth) and instead, it takes the A record of the domain address it is 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 name and not only will it be directed to the website that you have created, but it will also appear in the browser address bar at all times. Other possible uses of a CNAME record are to redirect all of the targeted traffic from different subdomains to their main domain, or to use the webmail service of your webhosting company by using webmail.your-doman.com, for instance. The latter will work only by setting up a CNAME record for a subdomain because this type of a record created for the main domain address renders it impossible to use email addresses.
