There are several ways to point a domain to an alternative domain or subdomain and one of them is by creating a CNAME record. In case you own a domain name and you have developed a site through some on-line service which supplies you with a service subdomain, you could easily link the two by setting up a CNAME record for your-domain.com that points to subdomain.provider.com. What you will achieve in this way 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 very important to know that if you set up a CNAME record, any other records your domain name may have will stop working, 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 more configuration may be required with the other company.
