Here's the question I challenged some of you to work out while we were looking at the output of the <em>ipconfig</em> command on a Windows computer within the CPS network.

Each school "owns" some range of CPS-internal (NATted) IP addresses, starting from the address of their gateway (router).  For instance, a random lab computer might show the <em>ipconfig</em> output of

this computer's IP address:     10.34.41.157

Subnet mask:     255.255.240.0

Gateway: 10.34.32.0

At every other Instructional (classroom and lab) computer in the same school, the Gateway and Subnet Mask will be the same as shown.   The this-computer-IP-address will be different of course.  Going to a different school,
