Basically it's a matter of whether the two networks are connected, an
easy question is

"If you took a machine with a 172.16.1.0 address, changed it to be
172.16.0.0, would it be able to talk to other hosts on the 172.16.0.0
network"

Or are they actually two physically separate networks with a router in
the middle.

Cheers,
Trent
