If you want to direct a domain name that you have to another domain or subdomain, a good way to do that would be to use a CNAME record. By setting up such a record, the domain address being pointed loses all of its records (A, MX, and so forth) and instead, it takes the A record of the domain name it's directed to. In this way, if you are using 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 website which you have created, but it'll also be displayed in the Internet browser address bar at all times. Some other possible uses of a CNAME record are to forward all of the traffic from various subdomains to their main Internet domain, or to use the webmail service of your hosting company by using webmail.your-doman.com, for instance. The latter will work only by creating a CNAME record for a subdomain due to the fact that such a record set up for the main domain makes it impossible to use e-mail addresses.
