*q*, a ``dns.message.Message``, the query to send.
*where*, a ``str``, the nameserver IP address or the full URL. If an IP address is
given, the URL will be constructed using the following schema:
https://:/.
*timeout*, a ``float`` or ``None``, the number of seconds to wait before the query
times out. If ``None``, the default, wait forever.
*port*, a ``int``, the port to send the query to. The default is 443.
*source*, a ``str`` containing an IPv4 or IPv6 address, specifying 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.
*ignore_trailing*, a ``bool``. If ``True``, ignore trailing junk at end of the
received message.
*session*, an ``httpx.Client``. 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 resolution.
*verify*, a ``bool`` or ``str``. If a ``True``, then TLS certificate verification
of the server is done using the default CA bundle; if ``False``, then no
verification is done; if a `str` then it specifies the path to a certificate file or
directory which will be used for verification.
*resolver*, a ``dns.resolver.Resolver`` or ``None``, the resolver to use for
resolution of hostnames in URLs. If not specified, a new resolver with a default
configuration will be used; note this is *not* the default resolver as that resolver
might have been configured to use DoH causing a chicken-and-egg problem. This
parameter only has an effect if the HTTP library is httpx.
*family*, an ``int``, the address family. If socket.AF_UNSPEC (the default), both A
and AAAA records will be retrieved.
*http_version*, a ``dns.query.HTTPVersion``, indicating which HTTP version to use.
Returns a ``dns.message.Message``.

mismatches occur, ignore them and keep listening for a valid response.
The default is ``False``.

*where*, a ``str`` containing an IPv4 or IPv6 address, where
to send the message.
*zone*, a ``dns.name.Name`` or ``str``, the name of the zone to transfer.
*rdtype*, an ``int`` or ``str``, the type of zone transfer. The
default is ``dns.rdatatype.AXFR``. ``dns.rdatatype.IXFR`` can be
used to do an incremental transfer instead.
*rdclass*, an ``int`` or ``str``, the class of the zone transfer.
The default is ``dns.rdataclass.IN``.
*timeout*, a ``float``, the number of seconds to wait for each
response message. If None, the default, wait forever.
*port*, an ``int``, the port send the message to. The default is 53.
*keyring*, a ``dict``, the keyring to use for TSIG.
*keyname*, a ``dns.name.Name`` or ``str``, the name of the TSIG
key to use.
*relativize*, a ``bool``. If ``True``, all names in the zone will be
relativized to the zone origin. It is essential that the
relativize setting matches the one specified to
``dns.zone.from_xfr()`` if using this generator to make a zone.
*lifetime*, a ``float``, the total number of seconds to spend
doing the transfer. If ``None``, the default, then there is no
limit on the time the transfer may take.
*source*, a ``str`` containing an IPv4 or IPv6 address, specifying
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.
*serial*, an ``int``, the SOA serial number to use as the base for
an IXFR diff sequence (only meaningful if *rdtype* is
``dns.rdatatype.IXFR``).
*use_udp*, a ``bool``. If ``True``, use UDP (only meaningful for IXFR).
*keyalgorithm*, a ``dns.name.Name`` or ``str``, the TSIG algorithm to use.
Raises on errors, and so does the generator.
Returns a generator of ``dns.message.Message`` objects.

for IXFRs. The default is ``dns.UDPMode.NEVER``, i.e. only use
TCP. Other possibilities are ``dns.UDPMode.TRY_FIRST``, which
means "try UDP but fallback to TCP if needed", and
``dns.UDPMode.ONLY``, which means "try UDP and raise
``dns.xfr.UseTCP`` if it does not succeed.
