There are lots of ways to direct a domain to an alternative domain or subdomain and one of them is by creating a CNAME record. In case you own a domain and you have developed a website using some on-line service which supplies you with a service subdomain, you can easily link the two by setting up a CNAME record for your-domain.com that redirects to subdomain.provider.com. What you will 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 provider. It is important to know that if you set up a CNAME record, any other records your domain address may have will stop functioning, so you cannot have both a CNAME record directing to one company and functioning email addresses with another. The CNAME record is always an alpha string, not a number, and often more configuration may be needed with the other company.
