In our network (at the physical cable level) there are many different network
protocols, internet addresses etc. I don't see any reason to force any one
protocol or internet address (anyone with any horror stories?). We have a
continuously growing number of sites connected via MAC level bridges and
have had no problems getting any ethernet device from any vendor to cross the
'boundaries'. So my experience shows that:

A) You do not HAVE to use the same internet address (or protocol) on a single
   physical media.

B) You do not HAVE to use different internet addresses for different segments
   connected via a MAC level bridge.

C) For management purposes you may WANT to implement different internet prefixes
