This document alters the specification defined in RFC 2535. Based
on implementation experience, the Authenticated Data (AD) bit in the
DNS header is not useful. This document redefines the AD bit such
that it is only set if all answers or records proving that no answers
exist in the response has been cryptographically verified or otherwise
meets the server's local security policy.
This document is a product of the DNS Extensions Working Group of the
IETF.
This is now a Proposed Standard Protocol.
