DNS query-answer matching algorithm differs from other DNS software

Usually DNS software matches responses to queries using tuple (src ip, src port, dst ip, dst port, transport protocol, msgid).

It seems that DNS collector now enforces match on QNAME, which is most likely cause of crash in issue #3 (closed) .

Using different matching algorithm than other DNS software will likely skew results, so I would recommend to use the same matching algorithm.
