Net::DNS is a perl implementation of a DNS resolver. .SH INSTALLATION .IX Header "INSTALLATION" .SS "Where can I find Test::More?" .IX Subsection "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 .SH USAGE .IX Header "USAGE" .ie n .SS "Why does $resolver\->\fBquery()\fP return undef when the answer section is empty?" .el .SS "Why does \f(CW$resolver\fP\->\fBquery()\fP return undef when the answer section is empty?" .IX Subsection "Why does $resolver->query() return undef when the answer section is empty?" The short answer is, do not use \fBquery()\fR. \&\f(CW$resolver\fR\->\fBsend()\fR will always return the response packet, as long as a response was received. .PP The longer answer is that \fBquery()\fR is modeled after the \fBres_query()\fR function from the libresolv C library, which has similar behavior. .SH VERSION .IX Header "VERSION" .Vb 1 \& $Id: FAQ.pod 1709 2018\-09\-07 08:03:09Z willem $ .Ve
