- We have some vendor-supplied equipment here which is hard-coded for
- an IP address that belongs to control data (the dreaded 192.9.200.x)
- since they had no understanding of how IP connectivity works and
- used the Sun default range. Unfortunately, this equipment can not
- be changed to use our correct IP address.

- If we have reverse pointers for the wrong IP address and never need
- connectivity to the real 192.9.200.x, do we need to worry about this
- external to our company as we join the internet? I would guess that
- the root servers would not acknolwedge that our domain owns that IP
- space in in-addr.arpa and therefore we'd never get external queries
- about this hardware. (Also, those machines will never ever talk to
- the internet.)

- Incorrect resource records have an annoying way of propogating
- themselves to other parts of the network. Doing this would, in my
- opinion, be a very bad idea. DNS programs assume (and should) that
- people don't do things like you suggest (because it is strongly
- discouraged) and as a result, don't segregate records at all. Also,
- assuming that you never need to send mail to CDC is a bad decision.
- Are you willing to make that guarantee for ten years? If not, you
- shouldn't set things up this way.
-
- If you just purchased the equipment, I would return it for refund,
- with a nastily worded letter explaining that you understood it could
- support TCP/IP, as claimed, when in fact it cannot.
