That's because you asked the wrong questions.

What you want is to query for the NS records, which give the desired 

; <<>> DiG 9.4.1 <<>> us. ns
; (1 server found)

;us.                            IN      NS

us.                     172800  IN      NS      J.GTLD.BIZ.
us.                     172800  IN      NS      K.GTLD.BIZ.
us.                     172800  IN      NS      A.GTLD.BIZ.
us.                     172800  IN      NS      B.GTLD.BIZ.
us.                     172800  IN      NS      C.GTLD.BIZ.
us.                     172800  IN      NS      I.GTLD.BIZ.

A.GTLD.BIZ.             172800  IN      A
B.GTLD.BIZ.             172800  IN      A
C.GTLD.BIZ.             172800  IN      A
I.GTLD.BIZ.             172800  IN      A
I.GTLD.BIZ.             172800  IN      AAAA 
J.GTLD.BIZ.             172800  IN      AAAA 
K.GTLD.BIZ.             172800  IN      A

Interestingly, J seems to only have an AAAA address. Bold move. :)

There is no way that query would get you what you're looking for. All 
it will produce is a referral, which is what you got. You could 
however substitute NS for SOA in this query too, and you'd once again 
get the right answer.



     If you're never wrong, you're not trying hard enough
