Windows subnets

[Donald Pearson]

Computers on the same subnet don't route to each other.  Routing is between
different networks.  All of your computers will be on the same
10.30.1.0/24network, in additional to their other respective networks.

So for example.

Computer A has the IPs
192.168.1.2/24
10.30.1.2/24

Computer B has the IPs
10.0.0.2/24
10.30.1.130/24

Computer A will be able to reach computer B using it's 10.30.1.130 IP
address, but not its 10.0.0.2 address.
