in light of the scarcity of IPs, no i don't have a good reason.

true to a degree. but it also makes it more difficult to move data
around between places though.

indeed... there is no security in IP, so to rely in any degree on IP
addresses for security is foolish. hence i wouldn't worry about
official IPs for most of the internal infrastructure stuff. if i have
cause to worry then i have a security problem elsewhere - and that
should be fixed.
