if I ask ns1/2/3/4/5/6.hp.com directly for AAAA for onramp01.hpeprint.com.:

;; QUESTION SECTION: ;onramp01.hpeprint.com. IN AAAA
You left out the authority section that refers you to the correct DNS servers - ns[1-6].hp.com are not it. They delegate to another set of HP servers, which all time out (as stated by the OP) when asked for AAAA. Oddly, it seems to be specific to AAAA; any other type request I send comes back NOERROR correctly. It is like somebody tried to handle AAAA "special" and screwed it up. -- Chris Adams <cma@cmadams.net>
