[Unbound-users] Modifying answer with the Python API

Bill Manning << You don't understand. It's not a problem for me as a
client, it's a problem for me as a worker at an internet provider. I have
to implement something totally broken because of what NTT did.
Daisuke Higashi << There is one little problem though: We would have to
write all IPv6 domains by hand in the configuration file.
In the end, I found that the only way to do this is to use the Python API.
But because Unbound doesn't offer any method to actually get the result of
the original query, I have to wait for the MODULE_EVENT_MODDONE to get the
result of the query and to be able to modify it. But then, because RRData
is all in wireformat, I have to convert all of them by hand which will take
a lot of effort to implement...
