DNS Query Support
=================

The ``dns.asyncquery`` module is for sending messages to DNS servers, and
processing their responses.  If you want "stub resolver" behavior, then
you should use the higher level ``dns.asyncresolver`` module; see
:ref:`async_resolver`.

For UDP and TCP, the module provides a single "do everything" query
function, and also provides the send and receive halves of this function
individually for situations where more sophisticated I/O handling is
being used by the application.
