If you want to direct a domain 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 on) and instead, it takes the A record of the domain name it is redirected to. 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 forwarded to the site you have set up, but it will also appear in the Internet browser address bar at all times. Other possible uses of a CNAME record are to point all the visitors from different 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 since this kind of a record set up for the main domain renders it impossible to use email addresses.
