Method lookupZone Perform an AXFR record lookup.
Instance Variable _ADDITIONAL_PROCESSING_TYPES Record types for which additional processing will be done.
Instance Variable _ADDRESS_TYPES Record types which are useful for inclusion in the additional section generated during additional processing.
Method _additionalRecords 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.
Method _lookup Determine a response to a particular DNS query.
Method _cbAllRecords Undocumented
