Hello,

My question is about the fields in the dynamic update response.
As RFC 2136 describes there are 2 possible dynamic update responses:

I. The ZOCOUNT, PRCOUNT, UPCOUNT, COUNT fields and associated sections are 
copied in the response packet
II. Placing zeros (0) in the these "count" fields and not including any part of 
the original update
Bind seems to follow the second rule.
Is it possible to configure Bind server to copy the ZOCOUNT, PRCOUNT, UPCOUNT 
and ADCOUNT fields and associated sections in the response packet?

RFC 2136:

 Dynamic Updates in the Domain Name System (DNS UPDATE)3.8 - Response    At the 
end of UPDATE processing, a response code will be known. A   response message 
is generated by copying the ID and Opcode fields   from the request, and either 
copying the ZOCOUNT, PRCOUNT, UPCOUNT,   and ADCOUNT fields and associated 
sections, or placing zeros (0) in   the these "count" fields and not including 
any part of the original   update. The QR bit is set to one (1), and the 
response is sent back   to the requestor. If the requestor used UDP, then the 
response will   be sent to the requestor's source UDP port. If the requestor 
used   TCP, then the response will be sent back on the requestor's open TCP   
connection.
Thanks in advance.

Best Regards,

Jack
