There are various ways to direct a domain to another domain or subdomain and one of them is by setting up a CNAME record. When you own a domain name and you've set up a website through some on-line service which provides 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 with this is that www.your-domain.com is going to be in the web browser address bar while it opens the already mentioned Internet site from the servers of the third-party provider. It is very important to 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 working e-mail address with a different one. The CNAME record is always an alpha string, not a number, and sometimes additional configuration may be required with the other provider.
