*where*. If the inference attempt fails, AF_INET is used. This
parameter is historical; you need never set it.
*zone*, a ``dns.name.Name`` or ``text``, the name of the zone to transfer.
*rdtype*, an ``int`` or ``text``, 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 ``text``, 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 ``text``, 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.
*af*, an ``int``, the address family to use. The default is ``None``,
which causes the address family to use to be inferred from the form of
*where*. If the inference attempt fails, AF_INET is used. This
parameter is historical; you need never set it.
*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 ``text`` 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 ``text``, the TSIG algorithm to use.
Raises on errors, and so does the generator.
Returns a generator of ``dns.message.Message`` objects.
