# chaos The *chaos* middleware 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-`, if not set. * **AUTHORS** is what authors to return. No default. Note that you have to make sure that this middleware will get actual queries for the following zones: `version.bind`, `version.server`, `authors.bind`, `hostname.bind` and `id.server`. ## Examples ~~~ chaos CoreDNS-001 "Miek Gieben" miek@miek.nl ~~~
