There are several ways to redirect a domain to a different domain or subdomain and one of them is by creating a CNAME record. In case you own a domain name and you've created a site through some on-line service that provides 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 are going to achieve as a result is that www.your-domain.com is going to be in the Internet browser address bar while it opens the already mentioned site from the servers of the third-party provider. It is essential 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 directing to one provider and working email addresses with a different one. The CNAME record is always an alpha string, not a number, and sometimes further configuration may be needed with the other provider.
