Return a tuple of dns.RRHeader
instances for all of the IPv4 addresses in the hosts file.
Return a tuple of dns.RRHeader
instances for all of the IPv6 addresses in the hosts file.
Generate a response for the given name containing the given result records, or a failure if there are no result records.
Parameters | name | The DNS name the response is for. (type: str ) |
records | A tuple of dns.RRHeader
instances giving the results that will go into the response. | |
Returns | A Deferred
which will fire with a three-tuple of result records, authority records,
and additional records, or which will fail with dns.DomainError
if there are no result records. |
