If you would like to point a domain address that you have to some other 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 redirected loses all its records (A, MX, and so forth) and instead, it takes the A record of the domain it's pointed to. In this way, if you use 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 website you have set up, but it will also appear in the browser address bar at all times. Other possible uses of a CNAME record are to redirect all 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 instance. The latter will work only by setting up a CNAME record for a subdomain due to the fact that such a record set up for the main domain address renders it impossible to use email addresses.
