If you would like to direct a domain that you have to some other domain address or subdomain, one way to do this would be to use a CNAME record. By creating such a record, the domain address being redirected loses all of its records (A, MX, etc) and instead, it takes the A record of the domain address it's directed to. By doing this, 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 forwarded to the website that you have set up, but it'll also be displayed in the Internet browser address bar at all times. Some other possible uses of a CNAME record are to redirect all the targeted traffic from various subdomains to their main domain address, or to use the webmail service of your hosting company by using webmail.your-doman.com, for example. The latter will work only by setting up a CNAME record for a subdomain because this type of a record set up for the main domain name makes it impossible to use e-mail addresses.
