Description Mark Andrews 2017-08-07 05:09:26 CEST
While RFC 6303 permits local zones to answer these names they still
need to follow all the resolution rules.  DS records for these names
belong to the parent zone and as long as the client is requesting
recursion and the server allows recursion for the client they the
query should recurse.

Hi Mark,

Yes you are right.  Nasty for downstream lookups of nxdomains (or nonDNSSEC trust points) for those DS records, who then don't get the recursive lookup for the DS record but a canned nodata answer.

Best regards, Wouter
