I make DNS zone transfer request (aka AXFR) via TCP to the server. The
answer is too big (>100Kb), so it could not be sent in one TCP
message. So the server send me a sequence of messages.

How can I determine which message is the last? I can't found anything
about it's count in the first message. I can't found any special flag
in the last one. I can't found anything about it in RFC1035.

Could you please explain how to find "end of answer"?
