Hmm, perhaps I misunderstood your original question. Did you actually ask if we checked the problematic server ignored all the 65535 (2^16 - 1) RR types? If so, the answer is no. We only tested against AAAA, MX, SOA, and NS (perhaps A6 or some other types). Also, for the "ignore" case, the checking side cannot be sure if the authoritative server really ignores the query or some intermediate node drops the query or the response. That's why we used the word "apparently" in the draft. And, you seem to require the authors to be more concrete (for example, "we tried to send queries for AAAA, MX, SOA, NS, ...and XX, and waited for yy seconds. We did not get any responses.") Not sure if the "redundant but perfectly accurate" wording is the best way, but I'll keep this in mind for the next revision (if any). JINMEI, Tatuya Communication Platform Lab.
