<div dir="ltr">Hi, Victor,<div>Would you mind checking the list for domains with broken signed delegations to anything matching *.<a href="http://domaincontrol.com">domaincontrol.com</a> (GoDaddy's nameservers), including categorization (e.g. lame NS, vs non-lame NS with broken signature)?</div><div>My suspicion is there may be a bunch of lame delegations, and knowing which TLDs (and if possible domains!) would be greatly appreciated.</div><div>Cleaning up lame delegations is neither easy nor fast, but we do want to actually clean them up.</div><div><br></div><div>(The root issue is there is currently no path for the delegatee to get the lame delegation removed. None. Nada. :-( )</div><div><br></div><div>Thanks,</div><div>Brian</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Oct 29, 2020 at 10:59 PM Viktor Dukhovni <<a href="mailto:ietf-dane@dukhovni.org">ietf-dane@dukhovni.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">I have a list of ~69k domain names with extant DS RRsets, where the<br>
DNSKEY RRset has been either unavailable or failing validation for 180<br>
days or more (92k domains if the bar is set to 90 days). These span 439<br>
TLDs! Of these domains, ~30k are simply lame and zone apex NS lookups<br>
fail even with CD=1. The remaining ~39k likely have DNSSEC-specific<br>
misconfiguration.<br>
<br>
The top 25 TLDs by count of long-term dead signed delegations are:<br>
<br>
24742 com<br>
9258 nl<br>
5357 se<br>
4553 cz<br>
2897 net<br>
2763 eu<br>
2044 pl<br>

349 sk<br>
346 dk<br>
321 app<br>
282 io<br>
250 biz<br>
240 pt<br>
<br>
If any of the TLDs have policies that allow the deadwood to be delisted<br>
(still registered, but not delegated) I can provide the list of<br>
domains... It would be nice to see less breakage in the live zones.<br>
