There are lots of ways to redirect a domain address to another domain or subdomain and one of them is by setting up a CNAME record. If you own a domain and you've created 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 redirects to subdomain.provider.com. What you will 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 provider. You should 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 functioning e-mail address with another one. The CNAME record is always an alpha string, not a number, and sometimes additional configuration may be needed with the other company.
