There are numerous ways to redirect a domain to another domain or subdomain and one of them is by creating a CNAME record. When you own a domain name and you have set up a site using some on-line service which provides you with a service subdomain, you could easily link the two by creating a CNAME record for your-domain.com that directs to subdomain.provider.com. What you're going to achieve in this way 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 working, so you cannot have both a CNAME record directing to one company and working e-mail address with a different one. The CNAME record is always an alpha string, not a number, and in some cases further configuration may be necessary with the other company.
