For what it's worth, no, we never get bogus claims of spam originating from
our IP range.

This is going out on a limb, but your range of 192.68.75.0/24 looks a lot
like 192.168.75.0/24 (which would be IANA reserved private) and that
confusion might be the source of your problem.

The "ooh, hackers are wizards that can do anything" theory requires one
observation and one assumption:

Observation: it's been noted that some of the esoteric hacks and/or DoS
attacks last year had come literally out of the ether due to injection of
dynamic routes into "public" systems.

Assumption: spammers are that smart.

We have a problem, where SpamCop or someone, will contact us claiming they
have received spam from our IP range. I investigate only to find out what I
expected, there is no server, client, or anything on that subnet. Infact we
haven't allocated that subnet yet, it sits unused.

My immediate suspicion is that the address is spoofed. We have bogon filters
on the edge of our network, so I am 99.9% sure that these are spoofed
addresses.
