There are several ways to redirect a domain name to an alternative domain or subdomain and one of them is by creating a CNAME record. When you own a domain and you have created a website using some on-line service which supplies 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 are going to achieve with this is that www.your-domain.com will be in the web browser address bar while it opens the already mentioned Internet 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 cannot have both a CNAME record directing to one company and working e-mail address with another. The CNAME record is always an alpha string, not a number, and in some cases additional configuration may be required with the other provider.
