If you would like to point a domain that you have to some other domain name or subdomain, a good way to do this would be to use a CNAME record. By creating such a record, the domain being redirected loses all its records (A, MX, and so forth) and instead, it takes the A record of the domain name it's pointed to. By doing this, 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 forwarded to the website 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 traffic from various subdomains to their main 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 because this kind of a record created for the main domain address renders it impossible to use email addresses.
