There is no difference.  An RFC1918 address is just as real as any
other IP address as far as any IP stack or network is concerned.  The
difference is that we, as humans, have decided those addresses are not
to cross certain boundaries, and it is up to us to make sure they
don't.  Except for my edge router, my other routers could care less
that I'm using RFC1918 addresses and in fact they don't know any
better.  I could just as easily stick my 207.160.213 network, another
"real" network, on there right alongside the 207.160.214 network (and
I did, at one time) with no problems.
