There are numerous 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've developed a website through 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 directs to subdomain.provider.com. What you are going to achieve by doing this is that www.your-domain.com will 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 important to know that if you set up a CNAME record, any other records your domain name may have will stop functioning, so you cannot have both a CNAME record pointing to one provider and working email addresses with another one. The CNAME record is always an alpha string, not a number, and sometimes additional configuration may be required with the other provider.
