If you'd like to forward a domain address that you have to a different domain name or subdomain, the best way to do this would be to use a CNAME record. By setting up such a record, the domain 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 directed to. 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 site you have created, but it will also appear in the Internet browser address bar at all times. Alternative possible uses of a CNAME record are to point all of the traffic from different subdomains to their main domain, or to use the webmail service of your hosting company by using webmail.your-doman.com, for example. The latter will work only by creating a CNAME record for a subdomain since this type of a record set up for the main domain address renders it impossible to use e-mail addresses.
