Hi,

 

I get some first experience finding when i try to query a non-existent domain the auth DNS response with no-error. below the capture dig response sample: (abc.co.id as example)

 

; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.68.rc1.el6_10.7 <<>> A +additional asdf.abc.co.id. @8.8.4.4
;; global options: +cmd
;; Got answer:
