Problems with DNS IXFR/AXFR
I have a problem with DNS IXFR/AXFR, that receives an answer in multiple packets. The situation is:
1- RFC1995 determines that IXFR can have an AXFR as a response;
2- RFC5936 says that AXFR can be sent over multiple responses.
So we have:
IXFR request -> Transaction ID 0x0001
First response -> Transaction ID 0x0001 (beginning with a SOA Type)
Following responses -> Transaction ID 0x0001 (until the end, ending with a SOA Type).
On responses from 2nd to last one, when clicking on the Transaction ID, wireshark says:
Expert Info (Warning/Protocol): DNS response retransmission. Original response in frame 340
Is it normal? Is there anything wrong with packets? Or wireshark is not ready for multiple response AXFR?
