There are several ways to point a domain name to an alternative domain or subdomain and one of them is by setting up a CNAME record. If you own a domain and you have developed a website using some online service which provides you with a service subdomain, you can 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 with this is that www.your-domain.com will be in the web browser address bar while it opens the already mentioned Internet site from the servers of the third-party company. It is very important to know that if you create a CNAME record, any other records your domain address may have will stop functioning, so you can't have both a CNAME record pointing to one company and functioning e-mail address with another. The CNAME record is always an alpha string, not a number, and sometimes further configuration may be required with the other provider.
