README

chaos

The chaos middleware allows CoreDNS to response to TXT queries in CH class. Useful for retrieving version or author information from the server.

Syntax

chaos [version] [authors...]

• version the version to return, defaults to CoreDNS.
• authors what authors to return. No default.

Note this middleware can only be specified for a zone once. This is because it hijacks the zones version.bind, version.server, authors.bind, hostname.bind and id.server, which means it can only be routed to one middleware.

Examples

chaos CoreDNS-001 "Miek Gieben" miek@miek.nl
