If you'd like to direct a domain address that you have to some other domain or subdomain, a good way to do this would be to use a CNAME record. By creating such a record, the domain name being pointed loses all its records (A, MX, and so forth) and instead, it takes the A record of the domain name it's pointed to. In this way, if you are using a web design service by some company that gives you a subdomain, you can use an actual domain name and not only will it be directed to the website that you've created, but it'll also be displayed in the Internet browser address bar at all times. Alternative possible uses of a CNAME record are to forward all of the traffic from different 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 creating a CNAME record for a subdomain because this kind of a record created for the main domain name makes it impossible to use e-mail addresses.
