There are various ways to redirect a domain address to an alternative domain or subdomain and one of them is by setting up a CNAME record. In case you own a domain name and you've set up a site using some on-line service which provides you with a service subdomain, you could easily link the two by setting up a CNAME record for your-domain.com that points to subdomain.provider.com. What you'll achieve as a result is that www.your-domain.com will be in the browser address bar while it opens the already mentioned Internet site from the servers of the third-party provider. It is essential 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. The CNAME record is always an alpha string, not a number, and in some cases more configuration may be necessary with the other company.
