Unbound Python module: examine response just before it's send to the client

Goal

I would like to examine the response just before it's dispatched to the client. Primarily, I'm interested in the ;; ANSWER SECTION:.

Problem

What had looked like a trivial modification of logDnsMsg function turned out to be a dounting task of browsing reply_info, rrset_ref and ub_packed_rrset_key structures in pursuit of the desired ;; ANSWER SECTION: bytes.

The reason is the logDnsMsg function does not work as expected for A queries ;; ANSWER SECTION:, while it suprisingly operates as expected for ;; AUTHORITY SECTION: on AAAA queries.
