This is just to update the list, the problem is indeed someone not
following the regulations.  As you can see from the output below,
someone is running an entire (unapproved) network in their office.
Probably they want WiFi since the official WiFi is pretty weak in our
building.

In the output below, 192.168.0.114 is the IP my laptop gets assigned.

# nmap -sn 192.168.0.0-255

Thanks for all the pointers and discussion.  It was quite educational
for me.
