There are multiple problems with p4.no, and you can see it with the
ISC EDNS compliance tester:


Note that there are more problems than those related to EDNS handling.
For instance, if I query without the "Recursion Desired" flag, the flag
is still set in the reply, which shouldn't happen:

% dig +norec +noad +noedns soa p4.no @
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 45201
;; flags: qr aa rd; QUERY: 1, ANSWER: 1, AUTHORITY: 2, ADDITIONAL: 5

This is the first test that the ISC EDNS compliance tester shows as
failing for p4.no.
