Christian,
as far as I can tell (without having access to the relevant servers)
this is possibly a misconfiguration on the primary.
I've taken a look in the zonefile we have for 197.193.in-addr.arpa and there
is no delegation for 192.197.193.in-addr.arpa within that file so
ns.ripe.net does not know where to send you. My guess is that the LIR have
the child zone configured on their server and that is why they are answering
differently.
