The Domain Name System (DNS) specifies a query type (QTYPE) "ANY".
The operator of an authoritative DNS server might choose not to
respond to such queries for reasons of local policy, motivated by
security, performance, or other reasons.
The DNS specification does not include specific guidance for the
behavior of DNS servers or clients in this situation. This document
aims to provide such guidance.
This document updates RFCs 1034 and 1035.
This document is a product of the Domain Name System Operations Working Group of the IETF.
This is now a Proposed Standard.
STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements. Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the
