There are lots of ways to redirect a domain address to a different domain or subdomain and one of them is by setting up a CNAME record. If you own a domain and you've set up a website through some on-line service that 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 with this is that www.your-domain.com is going to be in the Internet 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 create a CNAME record, any other records your domain address may have will stop working, so you can't have both a CNAME record pointing to one provider and working e-mail address with another. The CNAME record is always an alpha string, not a number, and sometimes more configuration may be needed with the other provider.
