If you wish to forward a domain address that you have to another domain address or subdomain, a good way to do this would be to use a CNAME record. By setting up such a record, the domain being redirected loses all of its records (A, MX, and so forth) and instead, it takes the A record of the domain address it is forwarded to. This 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 Internet site you have set up, but it'll also appear in the browser address bar at all times. Alternative possible uses of a CNAME record are to forward all of the visitors from various subdomains to their main domain name, 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 makes it impossible to use email addresses.
