# chaos

*chaos* allows CoreDNS to respond to TXT queries in the CH class.

This is useful for retrieving version or author information from the server.

## Syntax

~~~
chaos [VERSION] [AUTHORS...]
~~~

* **VERSION** is the version to return. Defaults to `CoreDNS-<version>`, if not set.
* **AUTHORS** is what authors to return. No default.

Note that you have to make sure that this plugin will get actual queries for the
following zones: `version.bind`, `version.server`, `authors.bind`, `hostname.bind` and
`id.server`.

## Examples

Specify all the zones in full.

~~~ corefile
version.bind version.server authors.bind hostname.bind id.server {
    chaos CoreDNS-001 info@coredns.io
}
~~~

Or just default to `.`:

~~~ corefile
.  {
    chaos CoreDNS-001 info@coredns.io
}
~~~

And test with `dig`:

~~~ txt
% dig @localhost CH TXT version.bind
...
;; ANSWER SECTION:
version.bind.		0	CH	TXT	"CoreDNS-001"
...
~~~
