If you would like to point a domain name that you have to a different domain or subdomain, one of the ways to do this would be to use a CNAME record. By creating such a record, the domain being redirected loses all of its records (A, MX, etc) and instead, it takes the A record of the Internet domain it is forwarded to. This way, if you use a web design service by some company that gives you a subdomain, you can use an actual domain and not only will it be directed to the website which you have created, but it will also appear in the web browser address bar at all times. Some other possible uses of a CNAME record are to point all of 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 example. The latter will work only by setting up a CNAME record for a subdomain since this type of a record set up for the main domain name makes it impossible to use e-mail addresses.
