The IANA Functions Operator has reviewed draft-dashevskyi-dnsrr-antipatterns-03 and has the following comments:

We understand that this document doesn't require any registry actions.

While it's often helpful for a document's IANA Considerations section to remain in place upon publication even if there are no actions, if the authors strongly prefer to remove it, we do not object.

If this assessment is not accurate, please respond as soon as possible.

draft-dashevskyi-dnsrr-antipatterns  has been presented to the ISE for
publication as an Informational RFC on the Independent Stream.

==Purpose==

This draft discusses some common mistakes that are made in DNS
implementations, and some recommendations to address those mistakes.
These include various failures to properly validate input.

== History==

This draft was submitted to the ISE on the 23rd of March, 2021.  It
was introduced to the DNSOP group a on the 4th of May, 2021, and
received some discussion, but did not progress there. The draft thus
remained with the ISE.

==Non-IETF Work==

This draft is the result of independent analysis of several
implementations.  There is no standards activity taking place
anywhere, to my knowledge, involving this work.

==Security Considerations==

This draft discusses several problematic implementation errors that
can lead to vulnerabilities.  To the best of my knowledge, the
approaches proposed to resolve them do not introduce new
vulnerabilities.


==IANA==

The document makes no request for IANA action.

==Reviews==

This document was reviewed by Peter Koch, and found to be worthy of
publication.
