\section introduction Introduction

The goal of ldns is to simplify DNS programming, it supports recent RFCs
like the DNSSEC documents, and allow developers to easily create software
conforming to current RFCs, and experimental software for current Internet
drafts. A secondary benefit of using ldns is speed, because ldns is written
in C, and although it is not optimized for performance, it should be a lot
faster than Perl.

The first main tool to use ldns is Drill, from which part of the library was
derived. From version 1.0.0 on, drill is included in the ldns release
and will not be distributed separately anymore. The library also includes some
other examples and tools to show how it can be used. These can be found in the
examples/ directory in the tarball.

ldns depends on OpenSSL for it's cryptographic functions.
Feature list

  - Transparent IPv4 and IPv6 support (overridable if necessary),
  - TSIG support,
  - DNSSEC support; signing and verification,
  - small size,
  - online documentation as well as manual pages.

If you want to send us patches please use the code from git.

\section using_ldns Using ldns

Almost all interaction between an application and ldns goes through the ldns
data structures (\ref ldns_rr, \ref ldns_pkt, etc.). These are input or
output to the functions of ldns. For example, \ref ldns_zone_new_frm_fp
reads a zone from a \c FILE pointer, and returns an \ref ldns_zone
structure.


Let's use Drill as an example. Drill is a tool much like dig, whose most
basic function is to send 1 query to a nameserver and print the response.

To be able to do this, drill uses the resolver module of ldns, which acts as
a stub resolver. The resolver module uses the net module to actually send
the query that drill requested. It then uses the wire2host module to
translate the response and place it in ldns' internal structures. These are
passed back to drill, which then uses the host2str module to print the
response in presentation format.

\section gettingstarted Getting Started

See the \ref design page for a very high level description of the design
choices made for ldns. 

For an overview of the functions and types ldns provides, you can check out
the \ref ldns ldns header file descriptions.

If you want to see some libdns action, you can read our tutorials:
  - \ref tutorial1_mx
  - \ref tutorial2_zone
  - \ref tutorial3_signzone

Or you can just use the menu above to browse through the API docs.
