def _additionalRecords(self, answer, authority, ttl): (source)
Find locally known information that could be useful to the consumer of the response and construct appropriate records to include in the additional section of that response.

Essentially, implement RFC 1034 section 4.3.2 step 6.

ParametersanswerA list of the records which will be included in the answer section of the response.
authorityA list of the records which will be included in the authority section of the response.
ttlThe default TTL for records for which this is not otherwise specified.
ReturnsA generator of dns.RRHeader instances for inclusion in the additional section. These instances represent extra information about the records in answer and authority.
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.
