There are numerous ways to point a domain name to a different domain or subdomain and one of them is by creating a CNAME record. When you own a domain and you have set up a site through some online service which supplies you with a service subdomain, you could easily link the two by setting up a CNAME record for your-domain.com that directs to subdomain.provider.com. What you are going to achieve by doing this is that www.your-domain.com is going to be in the Internet browser address bar while it opens the already mentioned site from the servers of the third-party company. 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 functioning e-mail address with a different one. The CNAME record is always an alpha string, not a number, and frequently further configuration may be needed with the other provider.
