There are many ways to redirect a domain address to another 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 creating a CNAME record for your-domain.com that directs to subdomain.provider.com. What you will 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 provider. You should know that if you set up a CNAME record, any other records your domain name may have will stop working, so you cannot have both a CNAME record directing to one provider and working e-mail address with another. The CNAME record is always an alpha string, not a number, and frequently further configuration may be required with the other company.
