Last Call Review of draft-ietf-dnsop-obsolete-dlv-00
review-ietf-dnsop-obsolete-dlv-00-secdir-lc-kelly-2019-10-03-00

I have reviewed this document as part of the security directorate's ongoing
effort to review all IETF documents being processed by the IESG.  These
comments were written primarily for the benefit of the security area directors.
 Document editors and WG chairs should treat these comments just like any other
last call comments.

The summary of the review is ready.

From the abstract, this document obsoletes DNSSEC lookaside validation (DLV)
and reclassifies RFCs 4431 and 5074 as Historic.

The document lists all current references to DLV RFCs and describes necessary
changes to those RFCs. The security considerations basically say that zones
relying on DLV will have to find another way, but that there are no well-known
DLV registries, so this number will likely be small.

I'm not a DNSSEC expert, so maybe this is a dumb question, but is there any
possibility that someone doesn't get the memo, and continues to rely on some
not-so-well-known DLV registry? And if so, what could happen as a result?
Anything anyone should care about?

Thanks,

Scott
