There are several ways to direct a domain 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 created a website using 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 Internet site from the servers of the third-party company. It is essential to know that if you set up a CNAME record, any other records your domain address may have will stop working, so you cannot have both a CNAME record pointing to one company and working email addresses with a different one. The CNAME record is always an alpha string, not a number, and in some cases further configuration may be necessary with the other company.
