If you'd like to direct a domain name 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 pointed loses all its records (A, MX, and so on) and instead, it takes the A record of the domain address it is redirected 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 and not only will it be directed to the Internet site that you have created, but it'll also be displayed in the web browser address bar at all times. Some other possible uses of a CNAME record are to forward all of the traffic from different 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 due to the fact that this kind of a record set up for the main domain renders it impossible to use email addresses.
