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. | |
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. | |
