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.
Parameters | |
server | 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:bytes | A bytes giving the domain to transfer. |
Returns | |
A new instance of SecondaryAuthority . |
Determine a response to a particular DNS query.
Parameters | |
name:bytes | The name which is being queried and for which to lookup a response. |
cls:int | The class which is being queried. Only IN is implemented here and this value is presently disregarded. |
type:int | The type of records being queried. See the types defined in twisted.names.dns . |
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. |
