domainThe domain for which this will be the secondary authority. (type: bytes or str)
@classmethod
def fromServerAddressAndDomain(cls, serverAddress, domain): (source)

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

ParametersserverAddressA 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.
domainA bytes giving the domain to transfer. (type: bytes)
ReturnsA new instance of SecondaryAuthority.
def transfer(self): (source)

Attempt a zone transfer.

ReturnsA Deferred that fires with None when attempted zone transfer has completed.
transfering = (source)

Undocumented

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

Determine a response to a particular DNS query.

ParametersnameThe name which is being queried and for which to lookup a response. (type: bytes)
clsThe class which is being queried. Only IN is implemented here and this value is presently disregarded. (type: int)
typeThe type of records being queried. See the types defined in twisted.names.dns. (type: int)
timeoutAll processing is done locally and a result is available immediately, so the timeout value is ignored.
ReturnsA 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.
