them harder to use in the future. RFC 103[45] doesn't say what to
do when the last reserved bit is used. Today we have queries
dropped, FORMERR'd, REFUSED'd, NOTIMP'd, and ignored. I really
don't care if the response is FORMERR, NOTIMP or ignored but we
should choose one and stomp out the others so that when we decide
to use the bit we don't have the mess [1] we had with the other
bits.
If that is something you want, this document is certainly not the
place to do it. That's a protocol specification change, and this
document is not altering the DNS protocol in any way.
Best regards,
Well reflecting back the bit isn't permitted and requiring that
such queries get answered are parts of the existing specification
which are not being followed. Requiring just these parts be correctly
followed will make future deployment easier.
As for the other see draft-andrews-no-response-issue.
