If you'd like to point a domain that you have to a different domain or subdomain, one way to do that would be to use a CNAME record. By creating such a record, the domain name being redirected loses all its records (A, MX, and so on) and instead, it takes the A record of the Internet domain it is directed 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 and not only will it be pointed to the site that you have created, but it will also be displayed in the Internet browser address bar at all times. Other possible uses of a CNAME record are to point all of the traffic from different subdomains to their main domain name, or to use the webmail service of your hosting provider by using webmail.your-doman.com, for example. The latter will work only by setting up a CNAME record for a subdomain because such a record created for the main domain address renders it impossible to use e-mail addresses.
