[dns-operations] NXDOMAIN vs NOERROR/no answers for non-existant records

[Matthew Richardson]

Thanks - I also had thought the NODATA response was wrong, but wanted a
second opinion...

However, is this going to cause any practical problems?

There are many domains being responded to in this way, and I do not think
any use DNSSEC.

Best wishes,
Matthew
