Sorry to break in on this thread and being off-topic, but...
CIDR is 10 years old! Anyone still thinking in class A and class C
is probably still using COBOL too... sigh

Anyway - are the windows machines able to talk to each other
even though they are in different networks ?

If yes - see how they do this. Perhaps there is a router for each
network somewhere, or some funky route add statements.

If not - then your approach with the 3 aliases is the right one,
except that you should make sure that you use unused IP addresses
to prevent clashes like you've experienced
