Extended DNS Errors
draft-ietf-dnsop-extended-error-15
Abstract
This document defines an extensible method to return additional
information about the cause of DNS errors. Though created primarily
to extend SERVFAIL to provide additional information about the cause
of DNS and DNSSEC failures, the Extended DNS Errors option defined in
this document allows all response types to contain extended error
information. Extended DNS Error information does not change the
processing of RCODEs.
