Either way - it breaks Sendmail, some versions of Exchange, and possibly
other MTA's. The proper answer to a non-existent AAAA record is
NOERROR, with ANSWER 0.
Hanging or refusing to answer doesn't result in another attempt to look
for an A record since the name server failed to respond to a valid
query. Given that the whole point of the domain is to enable email
printing, HP isn't making it easy.

Dear HP:
If your not going to support IPv6 can you at least not return
SRVFAIL when asked for an AAAA record:
They aren't. Your resolver is - or at least, that's what it looks
like for me.
Sending an AAAA query to their nameservers times out for me - no
response at all. Sending the same query through certain resolvers
(eg, Google) seems to result in the timeout being turned into a SERVFAIL.

Same via Google :
