CNAME Records

When do I use a CNAME record?

You will use a CNAME record when you want a subdomain to “point” to another website address.


It is not possible to use a CNAME record on just the bare domain (“”). It must be on a subdomain (“”). This is a technical constraint of this resource record type. For more on this please refer to the following (external link):

Can I have an example?

Here are a couple examples:

blog 10800 IN CNAME

www 10800 IN CNAME

The example CNAME records above will cause visitors to see a WordPress blog when they visit “” or “”.


The final dot (.) at the end is important. If you leave this out, your record will not work.
