There are several ways to redirect a domain name to a different domain or subdomain and one of them is by creating a CNAME record. In case you own a domain and you have developed a site using some on-line service which provides 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'll achieve with this is that www.your-domain.com will be in the 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 address may have will stop functioning, so you can't have both a CNAME record pointing to one provider and functioning e-mail address with another. The CNAME record is always an alpha string, not a number, and often further configuration may be necessary with the other company.
