If you would like to point a domain address that you have to another domain or subdomain, the best way to do this would be to use a CNAME record. By creating such a record, the domain being forwarded loses all of its records (A, MX, and so forth) and instead, it takes the A record of the domain address it is pointed to. That 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 redirected to the website that you have set up, but it will also appear in the browser address bar at all times. Some other possible uses of a CNAME record are to direct all of the traffic from various subdomains to their main domain name, or to use the webmail service of your webhosting company by using webmail.your-doman.com, for instance. 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 makes it impossible to use e-mail addresses.
