There are various ways to redirect a domain name to another domain or subdomain and one of them is by creating a CNAME record. When you own a domain and you've set up a site using some online service which supplies you with a service subdomain, you can easily link the two by creating a CNAME record for your-domain.com that directs to subdomain.provider.com. What you'll 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 Internet site from the servers of the third-party company. It is important to know that if you set up a CNAME record, any other records your domain may have will stop functioning, so you can't have both a CNAME record pointing to one company and functioning e-mail address with another. The CNAME record is always an alpha string, not a number, and frequently more configuration may be necessary with the other provider.
