I've never seen this on my network, but all my dialins use
either a routed network block, or a pool that is unique to each max,
with routes propagated via OSPF.
the only way something like what you describe should be possible is
if the isp is allowing you to request an address, or
giving you a static address that would normally appear
on the ethernet (causing the max to proxy arp for you).
one could argue that this is a poor design and should be
rethought in order to prevent things like a user dialing in
and requesting the ip address identical to the main mail server,
or to avoid the natural limitations of proxy arping timeouts.
the other possibility of course is that they are BS-ing you,
and the real issue is that they are still using RIP to do routing updates.
(they would want to make the problem SOUND difficult afterall)
