There are lots of ways to point a domain address to a different domain or subdomain and one of them is by creating a CNAME record. If you own a domain name and you have developed a website through some online service that provides you with a service subdomain, you could easily link the two by creating a CNAME record for your-domain.com that directs to subdomain.provider.com. What you are going to achieve as a result is that www.your-domain.com is going to be in the web browser address bar while it opens the already mentioned Internet 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 may have will stop functioning, so you can't have both a CNAME record directing to one provider and functioning e-mail address with another. The CNAME record is always an alpha string, not a number, and frequently further configuration may be needed with the other company.
