There are lots of ways to redirect a domain name to an alternative domain or subdomain and one of them is by creating a CNAME record. If you own a domain and you've created a site through some on-line service that provides 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 with this is that www.your-domain.com is going to be in the web browser address bar while it opens the already mentioned website from the servers of the third-party provider. You should know that if you set up a CNAME record, any other records your domain address may have will stop working, so you can't have both a CNAME record directing to one provider and working e-mail address with a different one. The CNAME record is always an alpha string, not a number, and frequently additional configuration may be required with the other provider.
