This document updates RFC 1035 by constraining the allowed value of
the QDCOUNT parameter in DNS messages with OPCODE = 0 (QUERY) to a
maximum of one, and it specifies the required behavior when values
that are not allowed are encountered.

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 
standardization state and status of this protocol.  Distribution of this 
memo is unlimited.
