There are numerous ways to point a domain to another 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 that provides you with a service subdomain, you can easily link the two by setting up a CNAME record for your-domain.com that directs to subdomain.provider.com. What you will achieve with this is that www.your-domain.com will be in the browser address bar while it opens the already mentioned Internet site from the servers of the third-party provider. You should know that if you set up a CNAME record, any other records your domain may have will stop working, so you cannot have both a CNAME record directing to one provider and functioning e-mail address with a different one. The CNAME record is always an alpha string, not a number, and sometimes more configuration may be needed with the other company.
