If you would like to direct a domain name that you have to some other domain or subdomain, one way to do that would be to use a CNAME record. By setting up such a record, the domain being redirected loses all of its records (A, MX, etc) and instead, it takes the A record of the Internet domain it is forwarded to. By doing this, if you are using a web design service by some company that gives you a subdomain, you can use an actual domain and not only will it be pointed to the Internet site that you've created, but it will also appear in the browser address bar at all times. Some other possible uses of a CNAME record are to forward all the targeted traffic from various subdomains to their main Internet domain, 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 since this type of a record set up for the main domain makes it impossible to use email addresses.
