There are many ways to point a domain to another domain or subdomain and one of them is by creating a CNAME record. When you own a domain name and you have 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 redirects to subdomain.provider.com. What you'll 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 site from the servers of the third-party provider. It is important to know that if you create a CNAME record, any other records your domain may have will stop functioning, so you cannot have both a CNAME record directing to one provider and functioning email addresses with another one. The CNAME record is always an alpha string, not a number, and sometimes additional configuration may be required with the other company.
