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.
