If you would like to direct a domain that you have to some other domain or subdomain, one way to do this would be to use a CNAME record. By creating such a record, the domain address being pointed loses all of its records (A, MX, and so on) and instead, it takes the A record of the domain name it's forwarded to. By doing this, 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 forwarded to the Internet site which you have set up, but it will also appear in the browser address bar at all times. Some other possible uses of a CNAME record are to direct all the targeted traffic from various subdomains to their main domain address, 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 kind of a record set up for the main domain address makes it impossible to use email addresses.
