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.
