There are various ways to redirect a domain name to another domain or subdomain and one of them is by creating a CNAME record. If you own a domain name and you've developed a site using some online service which supplies 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 are going to achieve as a result 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 important to know that if you create a CNAME record, any other records your domain name may have will stop functioning, so you cannot have both a CNAME record directing to one company and working email addresses with another. The CNAME record is always an alpha string, not a number, and in some cases more configuration may be required with the other company.
