=head1 NAME Net::DNS::FAQ - Frequently Asked Net::DNS Questions =head1 SYNOPSIS perldoc Net::DNS::FAQ =head1 DESCRIPTION This document serves to answer the most frequently asked questions on both the Net::DNS Mailing List and those sent to the author. The latest version of this FAQ can be found at L<http://www.net-dns.org/docs/FAQ.html> =head1 GENERAL =head2 What is Net::DNS? Net::DNS is a perl implementation of a DNS resolver. =head1 INSTALLATION =head2 Where can I find Test::More? Test::More is part of the Test-Simple package, by Michael G Schwern. You should be able to find the distribution at L<http://search.cpan.org/dist/Test-Simple/> =head1 USAGE =head2 Why does $resolver->query() return undef when the answer section is empty? The short answer is, do not use query(). $resolver->send() will always return the response packet, as long as a response was received. The longer answer is that query() is modeled after the res_query() function from the libresolv C library, which has similar behavior. =head1 VERSION $Id: FAQ.pod 1709 2018-09-07 08:03:09Z willem $
