@classmethod
def fromServerAddressAndDomain(cls, serverAddress, domain): (source)

Construct a new SecondaryAuthority from a tuple giving a server address and a str giving the name of a domain for which this is an authority.

Parameters	serverAddress	A two-tuple, the first element of which is a `str` giving an IP address and the second element of which is a `int` giving a port number. Together, these define where zone transfers will be attempted from.
	domain	A `str` giving the domain to transfer.
Returns	A new instance of `SecondaryAuthority`.

def _lookup(self, name, cls, type, timeout=None): (source)

Determine a response to a particular DNS query.

Parameters	name	The name which is being queried and for which to lookup a response. (type: `bytes`)
	cls	The class which is being queried. Only IN is implemented here and this value is presently disregarded. (type: `int`)
	type	The type of records being queried. See the types defined in `twisted.names.dns`. (type: `int`)
	timeout	All processing is done locally and a result is available immediately, so the timeout value is ignored.
Returns	A `Deferred` that fires with a `tuple` of three sets of response records (to comprise the answer, authority, and additional sections of a DNS response) or with a `Failure` if there is a problem processing the query.
