<p>Dear RSSAC Caucus,<br>
</p>
<p>A consortium of members from NLnet Labs and SIDN Labs has
conducted a study in response to a recommendation in a report of
the Root Zone Evaluation Committee (RZERC), namely RZERC002[1]
recommendation 2, quoted here:</p>
<blockquote>
<p>Recommendation 2: The RZERC recommends that ICANN org further
explore the cost / benefit tradeoffs and risks of signed root
zone name server data. Do the risks of redirected query traffic
outweigh the risks of increased operational complexity?<br>
</p>
</blockquote>
<p>This was an ICANN commissioned work. The report that is the
result of that study is attached to this e-mail.</p>
<p>Note that the same consortium also conducted the study that was
called for in the first recommendation of RZERC002, to conduct the
further studies called for in recommendation 2 of RSSAC028. Those
further studies were to understand the current behavior of DNS
resolvers and how each naming scheme discussed in the RSSAC028
document would affect these behaviors. We took on this study which
resulted in the "RSSAC028 Implementation study report" which is
published on the ICANN website here:<br>

class="moz-txt-link-freetext">https://www.icann.org/en/system/files/files/rssac028-implementation-study-report-27sep23-en.pdf</a></p>
<p>Since the "RSSAC028 Implementation study report" was in response
to RSSAC028 (which was originally a Caucus product), and because
"The reduced risk of redirected query traffic with signed root
name server data" report is a follow-up study to this (concluding
the recommendations of RZERC002), and because the root zone is of
interest to the root server system, I am sharing this here on the
RSSAC Caucus mailing-list.<br>
</p>
<p>Kind regards,</p>
<p> Willem Toorop on behalf of the responding to RZERC002
recommendation 2 consortium</p>
