This document serves to answer the most frequently asked questions on both the
Net::DNS Mailing List and those sent to the author.

Net::DNS is a perl implementation of a \s-1DNS\s0 resolver.

.el .SS "Why does \f(CW$resolver\fP\->\fIquery()\fP return undef when the answer section is empty?"
.IX Subsection "Why does $resolver->query() return undef when the answer section is empty?"
The short answer is, do not use \fIquery()\fR.
\&\f(CW$resolver\fR\->\fIsend()\fR will always return the response packet,
as long as a response was received.
.PP
The longer answer is that \fIquery()\fR is modeled after the \fIres_query()\fR function
from the libresolv C library, which has similar behavior.
