There are various ways to point a domain address to another domain or subdomain and one of them is by creating a CNAME record. In case you own a domain name and you've created a site using some on-line service that provides you with a service subdomain, you can easily link the two by creating a CNAME record for your-domain.com that points to subdomain.provider.com. What you're going to achieve in this way 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 company. It is essential 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 provider and functioning e-mail address with another. The CNAME record is always an alpha string, not a number, and in some cases further configuration may be needed with the other provider.
