There are numerous ways to direct a domain to a different 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 site using some online service which provides you with a service subdomain, you can easily link the two by creating a CNAME record for your-domain.com that redirects to subdomain.provider.com. What you are 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 website from the servers of the third-party company. It is very important to know that if you set up a CNAME record, any other records your domain address may have will stop functioning, 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 required with the other company.
