There are many ways to redirect a domain to a different domain or subdomain and one of them is by setting up a CNAME record. If you own a domain name and you've created a website through some on-line service which supplies 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 will achieve as a result is that www.your-domain.com is going to be in the browser address bar while it opens the already mentioned website from the servers of the third-party company. It is essential to know that if you create a CNAME record, any other records your domain may have will stop working, so you can't have both a CNAME record pointing to one provider and functioning e-mail address with another one. The CNAME record is always an alpha string, not a number, and frequently further configuration may be required with the other provider.
