There are several ways to direct a domain to an alternative domain or subdomain and one of them is by creating a CNAME record. If you own a domain name and you have developed a website through some on-line service which supplies you with a service subdomain, you can easily link the two by setting up a CNAME record for your-domain.com that redirects to subdomain.provider.com. What you'll achieve as a result is that www.your-domain.com will be in the Internet browser address bar while it opens the already mentioned website from the servers of the third-party company. It is important to know that if you set up a CNAME record, any other records your domain name may have will stop working, so you can't have both a CNAME record pointing to one company and working email addresses with another. The CNAME record is always an alpha string, not a number, and frequently further configuration may be needed with the other company.
