Hi Kevin,
First, my apologies. I somehow misplaced this email, and neither
responded to it at the time nor included it when going over all the
issues to address in the -03 draft, which was submitted this morning. I
was actually looking for something else in the mailing list archive
when I came across it. I am sorry to have overlooked it, and want to
be clear that this was entirely my mistake.

I understand this. I don't actually see why the expense might not be
a strong counter-consideration, if the expense were great; but there's
some text added in the -03 draft (to appear RSN) that I hope faces
this issue.

Yes, I see the problem, and you're right. What if it said instead,
"Unless there are strong counter-considerations, such as a high
probability of forcing large numbers of queries to use TCP, IP
addresses referenced in a forward mapping should have a
reverse mapping."
Would that address your concern?

I don't believe it is intended to preclude them. If you don't want to
use the DNS, then you obviously shouldn't need to use it. I think the
idea is that if you _do_ use the DNS forward, then you should also
provide the reverse mapping.
Thanks for the comments. If you like the proposed alteration, I'll
include it in an -04 version. Again, to you and the rest of the
working group, my apologies for having missed this.
Best regards,
Andrew
