There are several ways to direct a domain name to an alternative domain or subdomain and one of them is by setting up a CNAME record. If you own a domain name and you have created a website through some on-line service which supplies you with a service subdomain, you can easily link the two by creating a CNAME record for your-domain.com that redirects to subdomain.provider.com. What you're going to achieve in this way 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 company. You should know that if you create a CNAME record, any other records your domain address may have will stop working, so you cannot have both a CNAME record pointing to one company and working e-mail address with another. The CNAME record is always an alpha string, not a number, and in some cases additional configuration may be needed with the other company.
