If you wish to direct a domain name that you have to another domain address or subdomain, a good way to do that would be to use a CNAME record. By creating such a record, the domain name being redirected loses all its records (A, MX, etc) and instead, it takes the A record of the domain it's pointed to. By doing this, if you use a web design service by some provider that gives you a subdomain, you can use an actual domain name and not only will it be redirected to the site that you have set up, but it will also appear in the web browser address bar at all times. Some other possible uses of a CNAME record are to direct all of the targeted 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 because this type of a record created for the main domain name renders it impossible to use e-mail addresses.
