There are lots of ways to redirect a domain name to an alternative domain or subdomain and one of them is by setting up a CNAME record. When you own a domain name and you have set up 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 redirects to subdomain.provider.com. What you are going to 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 company. It is important to know that if you set up a CNAME record, any other records your domain may have will stop functioning, so you cannot have both a CNAME record pointing to one company and functioning e-mail address with another. The CNAME record is always an alpha string, not a number, and frequently more configuration may be necessary with the other company.
