There are numerous ways to direct a domain address to a different domain or subdomain and one of them is by creating a CNAME record. In case you own a domain and you've created a site through some on-line service which 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're going to achieve in this way is that www.your-domain.com will be in the web browser address bar while it opens the already mentioned Internet site from the servers of the third-party company. It is very important to know that if you create a CNAME record, any other records your domain address may have will stop working, so you can't 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 often more configuration may be needed with the other provider.
