if I ask ns1/2/3/4/5/6.hp.com directly for AAAA for onramp01.hpeprint.com.:
; <<>> DiG 9.8.1-P1 <<>> AAAA onramp01.hpeprint.com. @ns6.hp.com

;onramp01.hpeprint.com. IN AAAA
(I get the same result for all ns hosts)
if I ask my local bind (ubuntu package == 1:9.8.1.dfsg.P) though I get:
$ dig AAAA onramp01.hpeprint.com @localhost
; <<>> DiG 9.8.1-P1 <<>> AAAA onramp01.hpeprint.com @localhost

;; connection timed out; no servers could be reached
That's a bit weird and frustrating.

scott's request LOOKS like a request to 'some resolver' (not directly
to them, perhaps his local bind instance? I wonder why 8.8.8.8
returns srvfail? I think one of the google-public-dns people reads
nanog, perhaps he knows? (or could fix this which seems to be a bug,
to me at least)
