pycares is a Python module which provides an interface to c-ares. c-ares <http://c-ares.haxx.se>_ is a C library that performs DNS requests and name resolutions asynchronously.

Bundled c-ares

pycares currently bundles c-ares and as of pycares 1.0.0 this is a strong requirement. Upstream c-ares is not willing to apply a patch adding TTL support <http://c-ares.haxx.se/mail/c-ares-archive-2013-07/0005.shtml>_. I did apply the patch to the bundled c-ares, but unfortunately it breaks the ABI, so attempting to use a system provided c-ares is not possible.

Installation

GNU/Linux, macOS, Windows, others:

::

pip install pycares

FreeBSD:

::

cd /usr/ports/dns/py-pycares && make install

IDNA 2008 support ^^^^^^^^^^^^^^^^^

If the idna package is installed, pycares will support IDNA 2008 encodingm otherwise the builtin idna codec will be used, which provides IDNA 2003 support.

You can force this at installation time as follows:

::

pip install pycares[idna]

Running the test suite

There are several ways of running the test suite:

• Run the test with the current Python interpreter:

  From the toplevel directory, run: python tests/tests.py

• Use Tox to run the test suite in several virtualenvs with several interpreters

  From the toplevel directory, run: tox -e py35,py36,py37 this will run the test suite on Python 3.5, 3.6 and 3.7 (you'll need to have them installed beforehand)

Using it from the cli, a la dig

This module can be used directly from the command line in a similar fashion to dig (limited, of course):
