If you want to direct a domain name that you have to another domain or subdomain, a good way to do that would be to use a CNAME record. By creating such a record, the domain address being pointed loses all of its records (A, MX, and so on) and instead, it takes the A record of the Internet domain it is redirected to. That way, if you are using a web design service by some provider that gives you a subdomain, you can use an actual domain and not only will it be directed to the site you have set up, but it will 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 different subdomains to their main domain name, or to use the webmail service of your hosting provider by using webmail.your-doman.com, for instance. The latter will work only by setting up a CNAME record for a subdomain due to the fact that this kind of a record set up for the main domain name makes it impossible to use email addresses.
