All,
I read the source code recently,in the function answer_axfr_ixfr do not cover the case AXFR over UDP,so what’s the return value when the query type is AXFR over UDP?

Thanks very much.

Hi Lin,

Discarded, not implemented. The AXFR query is only allowed over TCP
transport and not allowed over UDP, by the RFC.

Best regards, Wouter
