Abstract:
This document defines an extensible method to return additional
information about the cause of DNS errors. The primary use case is
to extend SERVFAIL to provide additional information about the cause
of DNS and DNSSEC failures.
[ Open question: The document currently defines a registry for
errors. It has also been suggested that the option also carry human
readable (text) messages, to allow the server admin to provide
additional debugging information (e.g: "example.com pointed their NS
at us. No idea why...", "We don't provide recursive DNS to
192.0.2.0. Please stop asking...", "Have you tried Acme Anvil and
DNS? We do DNS right..." (!). Please let us know if you think text
is needed, or if a 16bit FCFS registry is expressive enough. ]
[ Open question: This document discusses extended *errors*, but it
has been suggested that this could be used to also annotate *non-
error* messages. The authors do not think that this is a good idea,
but could be persuaded otherwise. ]
