Providing Minimal-Sized Responses to DNS Queries That Have QTYPE=ANY
RFC 8482, “Providing Minimal-Sized Responses to DNS Queries That Have QTYPE=ANY”, is a Proposed Standard document published in January 2019 by J. Abley, O. Gudmundsson, M. Majkowski, E. Hunt. It updates RFC 1034, RFC 1035. The canonical text is published by the RFC Editor.
Abstract
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.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
