An asynchronous DNS resolver for Haskell_
=========================================

:Latest Release: hsdns-1.0.tar.gz_
:Darcs:          darcs_ get http://cryp.to/hsdns/

Synopsis
--------

  This library provides an asynchronous DNS resolver on top of
  the `GNU ADNS library`_. Not all options are supported, but A,
  MX, and PTR lookups work fine. The code has been been tested
  with ADNS versions 1.0 to 1.4.

  The example program adns-reverse-lookup.hs_ demonstrates how
  the resolver is used. Given a list of host names on the command
  line, it performs an A/PTR double-lookup and checks whether the
  records are consistent. The output is printed in the order in
  which the DNS responses arrive::

    $ ./adns-reverse-lookup xyz.example.org ecrc.de www.example.com www.cryp.to
    OK: www.example.com <-> 208.77.188.166
    ERR: xyz.example.org: cannot resolve A
    FAIL: www.cryp.to -> 195.234.152.69 -> ["research.cryp.to"]
    FAIL: ecrc.de -> 127.0.0.1 -> ["localhost"]
