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. This will send visitors who visit the subdomain in the CNAME record to a different 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.

If you want to point the domain name itself to another website, and not just a subdomain, you need to use an alias record.

Can I have an example?

Here are a couple examples:

blog 10800 IN CNAME

www 10800 IN CNAME

If your domain name is, the first example above will send visitors who go to to the wordrpess blog at

Likewise, the second example will also send visitors to to the same wordpress blog.


The final dot (.) at the end must be included for the record to function.
