(Question to group/list: does dig 9.3.1 rely on the configured resolver,
using gethostbyname or similar, to resolve the NS names to addresses,
ignoring any glue A in additional sections?  I've seen something that

Can you query those servers directly by IP address from dig, eg is, so

dig @ a +norec

should list the NS records for and the A records for those

;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 64477
;; flags: qr; QUERY: 1, ANSWER: 0, AUTHORITY: 3, ADDITIONAL: 3

;			IN	A

;; AUTHORITY SECTION:		86400	IN	NS		86400	IN	NS		86400	IN	NS

;; ADDITIONAL SECTION:	86400	IN	A	86400	IN	A	86400	IN	A

The other nameservers for are,, and, so you could try the above with them

Might as well ask: what's in your named.conf?
