The DNS is a query/response protocol. Failing to respond to queries,
or responding incorrectly, causes both immediate operational problems
and long-term problems with protocol development.
This document identifies a number of common kinds of queries to which
some servers either fail to respond or respond incorrectly. This
document also suggests procedures for zone operators to apply to
identify and remediate the problem.
The document does not look at the DNS data itself, just the structure
of the responses.
This document is a product of the Domain Name System Operations Working Group
of the IETF.
BCP: This document specifies an Internet Best Current Practices for the
Internet Community, and requests discussion and suggestions for
