[comp.dcom.lans] subnets

I have two general questions about subnetting in TCP/IP.

At Iowa State University we have a class B address and our
campus network consists of a four large bridged Ethernet segments
with a FDDI backbone used to connect these segments.  Some of the
segments contain IP Gateways.  The campus was using transparent subnetting
until about a month aao when the campus changed to unsubnetted.  The
Broadcast addresses and the Netmasks have been changed.
(Broadcast changed from 129.186.X.255 to 129.186.255.255 and the netmask
changed from 255.255.0.0 to 255.255.255.0).  The questions I are:

1)  Should we have changed the campus to not support transparent subnetting
even though we do have some true subnets within our domain.

2)  How do other organizations with class B addresses set up their networks
and do they use transparent subnetting.

You can mail your responses to me at doug@isuee1.ee.iastate.edu
if there is enough interest I will post the results to question 2.
