USAGE
Why does Net::DNS::Resolver::query() return undef when the ANSWER section is empty?
The short answer is, don't use query(). Net::DNS::Resolver::send() will always return the answer packet, as long as an answer was received.
The longer answer is that query() is modeled after the res_query() function from the libresolv C library, which has similar behaviors.
