If you'd like to point a domain name that you have to another domain name or subdomain, one of the ways to do this would be to use a CNAME record. By setting up such a record, the domain address being pointed loses all of its records (A, MX, and so forth) and instead, it takes the A record of the domain name it is directed to. In this way, if you use 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 redirected to the Internet site which you have created, but it will also be displayed in the browser address bar at all times. Some other possible uses of a CNAME record are to forward all of 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 instance. The latter will work only by creating a CNAME record for a subdomain simply because such a record created for the main domain renders it impossible to use email addresses.
