There are many ways to point a domain address to an alternative domain or subdomain and one of them is by creating a CNAME record. If you own a domain name and you have developed a site using some on-line service which provides you with a service subdomain, you can easily link the two by setting up a CNAME record for your-domain.com that directs to subdomain.provider.com. What you're going to achieve in this way 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 essential to know that if you create a CNAME record, any other records your domain may have will stop functioning, so you cannot have both a CNAME record directing to one company and functioning e-mail address with another. The CNAME record is always an alpha string, not a number, and frequently further configuration may be necessary with the other company.
