I've had enough trouble getting ISPs to support 2317 delegation period.

I invite you to go skim RFC 2317 -- Classless IN-ADDR.ARPA Delegation.
TL;DR: 2317 is a
an ancient csh script named `doc` used to be guiltily associated with
bind. i can no longer find it. i have 2.2.3 from 2001.07.25. anyone
know the whereabouts of anything more recent? 2.2.3 has a little bugy

Or do what should have been done in the first place and be a unlisted secondary
of 1.66.136.193.in-addr.arpa. This way David you track the changes your ISP
makes
to the zone as customers come and go. Your ISP should let you transfer this
zone as it
is REQUIRED for your reverse lookups to work
Come to think of it I don't have the trailing dot either.
I thought the dot was to terminate domain name qualification for forwarder
records.

Probably. Am I supposed to, I have just 2 segments in this network
(and 2 others on another work) ?
Normally no, you're not supposed to /need/ to have a copy of an
intermediate zone.
Thanks again.

The queries should work if you query an authoritative dns server for
that zone. If you are querying a recursive only server(when Internet
connection is down), it won't be able to find the authoritative server
and will answer only if it has valid cached answer. Once that cached
answer expires

What is the origin of your zone file? 0-28.66.136.193.in-addr.arpa.?

You seem to be using RFC 2317 Classless IN-ADDR.ARPA delegation.
As
Ok. This is public address space. Delegation for reverse zones is separate
from forward zones.
Kind of depends on where the connectivity failure is, as to whether or not
clients can walk the delegation tree (or need to). Then there's the effect
of TTLs expiring.

Not enough information is provided about how your PTR zone is configured
to allow anyone to provide a definitive answer. (Is this nonroutable
space? Where are the machines located? Are they talking directly to the
auth servers or are there recursives in the resolution path?)
