There are several ways to point a domain address to an alternative domain or subdomain and one of them is by setting up a CNAME record. When you own a domain and you've set up a website using some on-line service which provides you with a service subdomain, you can easily link the two by creating a CNAME record for your-domain.com that directs to subdomain.provider.com. What you'll achieve by doing this is that www.your-domain.com will be in the Internet browser address bar while it opens the already mentioned website from the servers of the third-party provider. It is important to know that if you create a CNAME record, any other records your domain may have will stop functioning, so you can't have both a CNAME record directing to one company and working e-mail address with a different one. The CNAME record is always an alpha string, not a number, and frequently further configuration may be necessary with the other company.
