Knot DNS capture from response_collector

Kept just a file output from response_collector.  The tree generator generates a rules with a lot of false positives (almost any DNS server is identified as Knot DNS if I merge them in).

You can also test running instances of Knot DNS:

pagan.rfc1925.org
mamlas.feela.net
knot-s-01.nic.cz
knot-g-01.nic.cz
or
selu.ns.nic.cz
