There are numerous ways to redirect a domain name to an alternative domain or subdomain and one of them is by setting up a CNAME record. In case you own a domain name and you have developed a site using some on-line service which supplies you with a service subdomain, you could easily link the two by creating a CNAME record for your-domain.com that redirects to subdomain.provider.com. What you will achieve by doing this is that www.your-domain.com will be in the Internet browser address bar while it opens the already mentioned Internet site from the servers of the third-party provider. It is very important to know that if you set up a CNAME record, any other records your domain may have will stop functioning, so you can't have both a CNAME record pointing to one provider and functioning email addresses with another. The CNAME record is always an alpha string, not a number, and in some cases additional configuration may be needed with the other company.
