There are many ways to redirect a domain name to another domain or subdomain and one of them is by setting up a CNAME record. In case you own a domain name and you've developed a site using some online 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 directs to subdomain.provider.com. What you'll achieve in this way is that www.your-domain.com will be in the web 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 functioning, so you cannot 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 often further configuration may be needed with the other company.
