# Net::DNS::FAQ(3pm)

Frequently Asked Net::DNS Questions

## NAME

Net::DNS::FAQ - Frequently Asked Net::DNS Questions

## SYNOPSIS

```
    perldoc Net::DNS::FAQ
```

## 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\
 	\<http://www.net-dns.org/docs/FAQ.html\>

## GENERAL

### What is Net::DNS?

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

## INSTALLATION

### 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\
 	\<http://search.cpan.org/dist/Test-Simple/\>

## USAGE

### 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.
