There are numerous ways to point a domain name to a different domain or subdomain and one of them is by setting up a CNAME record. If you own a domain name and you've developed a website using some online service which provides you with a service subdomain, you could easily link the two by creating a CNAME record for your-domain.com that points to subdomain.provider.com. What you will 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. It is important to know that if you set up a CNAME record, any other records your domain may have will stop functioning, so you cannot have both a CNAME record pointing to one company and working email addresses with another. The CNAME record is always an alpha string, not a number, and sometimes additional configuration may be needed with the other company.
