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