Ya- I see - your right the router is 10.54.7.1 The rest of the network
switches are hubs off of that (all still 10.54.7.)
this private network is truly private (independent to the 2 computers
connected) in other words they are off the network, their traffic oesn't
go through a switch.
I didn't give this enough thought ....
the fact is I dont need to connect to the 0 address directly from the
windows machine. The 0 address is only for private network between the
I was just curious that I couldn't ping them, I thought ping (and the
port scanner) should magically find them (like dns) ...
