Hello Pieter,

(I am the author of the mentioned dns software)

According to RFC1034, including the request in the response seem to be required.
Is there something I am misunderstanding here ?


4.3.1. Queries and responses

The principal activity of name servers is to answer standard queries.
Both the query and its response are carried in a standard message format
which is described in [RFC-1035].

I tested the wrong domain. p4.no indeed breaks because the auths respond
with a FORMERR plus an OPT record when EDNS is sent in the query. The
flagday site indeed does not seem to check this, but it is wrong
behaviour.

Best regards,

Pieter
