[DNSOP] .NU NSEC3 to NSEC roll over

2020-11-11 Thread Ulrich Wisser
Hi, .NU has for many years been signed with NSEC3. When the Swedish Internet foundation took over .nu in 2013 we continued with NSEC3. In 2017 we started to publish all zone files for .nu and .se (zonedata.iis.se). Since then we have wanted to do a roll over to NSEC. Today is that day! At 13

It occurs to me that for DMARC's purposes, walking up the tree would work better than the current hack. CAA records are perhaps less of a target for query amplification abuse than DMARC records :-) I dunno, seems to me the stakes are higher for CAA but the number of requests per domain are f
