Net::DNS is a perl implementation of a DNS resolver.

        http://search.cpan.org/dist/Test-Simple/

 

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.
