the source address. The default is the wildcard address.
*source_port*, an ``int``, the port from which to send the message.
The default is 0.
*one_rr_per_rrset*, a ``bool``. If ``True``, put each RR into its own
RRset.

junk at end of the received message.
*session*, an ``httpx.Client`` or ``requests.session.Session``. If
provided, the client/session to use to send the queries.
*path*, a ``str``. If *where* is an IP address, then *path* will be used to
construct the URL to send the DNS query to.
*post*, a ``bool``. If ``True``, the default, POST method will be used.
*bootstrap_address*, a ``str``, the IP address to use to bypass the
system's DNS resolver.
*verify*, a ``str``, containing a path to a certificate file or directory.
