There are several ways to redirect a domain address to another 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 setting up a CNAME record for your-domain.com that redirects to subdomain.provider.com. What you're 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 site from the servers of the third-party provider. It is important to know that if you set up a CNAME record, any other records your domain may have will stop working, so you can't have both a CNAME record directing to one provider and working e-mail address with another one. The CNAME record is always an alpha string, not a number, and sometimes further configuration may be necessary with the other provider.
