Knot DNS authoritative server に注目するのは、

https://lists.nic.cz/pipermail/knot-dns-users/2015-September/000700.html

We have decided to remove NS record from the Authority section for NOERROR responses. 
We used to put these records there because BIND and NSD did it.
But these records are not required by any RFC and just increase the size of the response.

でも、cz ccTLDなどの実際の運用には他のサーバソフトも併用されているため、 このことは目立ちにくい状況です。 -- ToshinoriMaeno 2015-10-17 06:14:45

たとえば、

dig -t ns cz @194.0.12.1

を実行しても、Knot サーバが答えるとはかぎらないのです。
