    @type keyring: dict
    @ivar keyname: The TSIG keyname to use.  The default is None.
    @type keyname: dns.name.Name object
    @ivar keyalgorithm: The TSIG algorithm to use; defaults to
    dns.tsig.default_algorithm.  Constants for TSIG algorithms are defined
    in dns.tsig, and the currently implemented algorithms are
    HMAC_MD5, HMAC_SHA1, HMAC_SHA224, HMAC_SHA256, HMAC_SHA384, and
    HMAC_SHA512.
    @type keyalgorithm: string
    @ivar request_mac: The TSIG MAC of the request message associated with
    this message; used when validating TSIG signatures.   @see: RFC 2845 for
    more information on TSIG fields.
    @type request_mac: string
    @ivar fudge: TSIG time fudge; default is 300 seconds.

    zone transfer?  The default is False.
    @type xfr: bool
    @ivar origin: The origin of the zone in messages which are used for
    zone transfers or for DNS dynamic updates.  The default is None.

    signature?
    @type had_tsig: bool
    @ivar multi: Is this message part of a multi-message sequence?  The
    default is false.  This variable is used when validating TSIG signatures
    on messages which are part of a zone transfer.
    @type multi: bool
    @ivar first: Is this message standalone, or the first of a multi
    message sequence?  This variable is used when validating TSIG signatures
    on messages which are part of a zone transfer.
    @type first: bool
    @ivar index: An index of rrsets in the message.  The index key is
    (section, name, rdclass, rdtype, covers, deleting).  Indexing can be

    The message returned is really a response skeleton; it has all
    of the infrastructure required of a response, but none of the
    content.

    The response's question section is a shallow copy of the query's
    question section, so the query's question RRsets should not be
    changed.

    @param query: the query to respond to
    @type query: dns.message.Message object
    @param recursion_available: should RA be set in the response?
    @type recursion_available: bool
    @param our_payload: payload size to advertise in EDNS responses; default
    is 8192.
    @type our_payload: int
    @param fudge: TSIG time fudge; default is 300 seconds.
