There are lots of ways to point a domain name to another domain or subdomain and one of them is by creating a CNAME record. In case you own a domain and you have created a site using some online service which supplies you with a service subdomain, you can easily link the two by creating a CNAME record for your-domain.com that points to subdomain.provider.com. What you're going to achieve as a result 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 very 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 functioning e-mail address with another one. The CNAME record is always an alpha string, not a number, and frequently more configuration may be needed with the other provider.
