The following dig query dig gov +dnssec +noadflag @10.10.10.1 produces the following flags in the header section: ;; flags: qr rd ra ad; Question - what is the relation with the +dnssec and +noadflag options in the query. I would think the query would produce a signed response with no ad bit in the header section. Why does ad show up when I specify +noadflag? Thanks!!
