If not ``None``, then the owner name is "forced", and the input must not specify an owner name. If ``None``, then any owner names are allowed and must be present in the input. *ttl*, an ``int``, string, or None. If not ``None``, the the TTL is forced to be the specified value and the input must not specify a TTL. If ``None``, then a TTL may be specified in the input. If it is not specified, then the *default_ttl* will be used. *rdclass*, a ``dns.rdataclass.RdataClass``, string, or ``None``. If not ``None``, then the class is forced to the specified value, and the input must not specify a class. If ``None``, then the input may specify a class that matches *default_rdclass*. Note that it is not possible to return rrsets with differing classes; specifying ``None`` for the class simply allows the user to optionally type a class as that may be convenient when cutting and pasting. *default_rdclass*, a ``dns.rdataclass.RdataClass`` or string. The class of the returned rrsets. *rdtype*, a ``dns.rdatatype.RdataType``, string, or ``None``. If not ``None``, then the type is forced to the specified value, and the input must not specify a type. If ``None``, then a type must be present for each RR. *default_ttl*, an ``int``, string, or ``None``. If not ``None``, then if the TTL is not forced and is not specified, then this value will be used. if ``None``, then if the TTL is not forced an error will occur if the TTL is not specified. *idna_codec*, a ``dns.name.IDNACodec``, specifies the IDNA encoder/decoder. If ``None``, the default IDNA 2003 encoder/decoder is used. Note that codecs only apply to the owner name; dnspython does not do IDNA for names in rdata, as there is no IDNA zonefile format. *origin*, a string, ``dns.name.Name``, or ``None``, is the origin for any relative names in the input, and also the origin to relativize to if *relativize* is ``True``. *relativize*, a bool. If ``True``, names are relativized to the *origin*; if ``False`` then any relative names in the input are made absolute by appending the *origin*.
