thanks for the clarification. I think we got a "works as designed"
situation: The flags are indeed numerically zero, as I can see in
wireshark... the full option 81 is like
0000 51 08 00 00 00 41 50 46 45 4c Q....APFEL
Okay for me -- thinking twice about the situation makes me wonder if my
initial expectation that we should get forward DNS entries is justified or
whether it is just fine that we dont have A DNS entries. Probably my
expectation was just motivated by symmetry...
Funny RFC, though... inverse logic between the N and S flags, where a value
of 0 indicates in one flag (N) that the server SHOULD perform (reverse) DNS
updates, and in the other value (S) it indicates the server SHOULD NOT
perform DNS (forward) updates.

Sounds to me like this makes a lot of sense.
Thanks again for looking into this.
