If you would like to direct 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 setting up such a record, the domain address being redirected loses all its records (A, MX, and so forth) and instead, it takes the A record of the domain name it's redirected to. By doing this, if you are using a web design service by some company that gives you a subdomain, you can use an actual domain name and not only will it be pointed to the website which you have set up, but it'll also appear in the Internet browser address bar at all times. Some other possible uses of a CNAME record are to point all the visitors from different subdomains to their main Internet 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 set up for the main domain address makes it impossible to use email addresses.
