draft I referenced in my previous email. It is currently an adopted WG =

closing soon. The second document does not appear to be associated with =
any IETF Working Group yet, but it also isn't competing with the first =
document. The first draft is informational status, discussing the issues =
and considerations surrounding this problem, of which generating =
on-the-fly reverse records is one possible solution. The second draft is =
a proposed standard defining *how* to generate those on-the-fly reverse =
records assuming one decides that is the right path to take in one's =
network, and would dovetail nicely via reference to section 2.5 of =
isp-ip6-rdns.
This is exactly right, and thanks for the clear explanation of arcane =

John Woodworth=E2=80=99s bulk-rr document was discussed in the WG in the =
