There are many ways to redirect a domain address to an alternative domain or subdomain and one of them is by creating a CNAME record. When you own a domain name and you've set up a website using some on-line service which supplies you with a service subdomain, you could 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 is going to 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 important to know that if you set up a CNAME record, any other records your domain name may have will stop functioning, so you can't have both a CNAME record pointing to one provider and functioning e-mail address with a different one. The CNAME record is always an alpha string, not a number, and sometimes additional configuration may be required with the other provider.
