-DNS performance
----------------
-
-You can often improve performance by providing one or more local nameservers
-to the CLI or function calls, as long as those nameservers return the same
-records as the public DNS.
-
-
-.. note::
-
-   If you do not specify any nameservers, Cloudflare's public nameservers are
-   used by default, **not the system's default nameservers**.
-
-   This is done to avoid a situation where records in a local nameserver do
-   not match records in the public DNS.
