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. @type fudge: int @ivar original_id: TSIG original id; defaults to the message's id @type original_id: int @ivar tsig_error: TSIG error code; default is 0. @type tsig_error: int @ivar other_data: TSIG other data. @type other_data: string @ivar mac: The TSIG MAC for this message. @type mac: string @ivar xfr: Is the message being used to contain the results of a DNS zone transfer?

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.
