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.
