We have all of our in house systems on a 10 network. We had 3 departments
fighting for addresses in the range of 10.0.0.1 - 10.0.0.254. I thought
this was silly, so I decided to move the QNX hosts to 10.1.X.X. After all,
everybody is a 10 net which is class A so they should have no problem
talking to each other.
I wasn’t able to ping the NT servers going from 10.1.X.X to 10.0.0.X. OK,
that’s an easy one. The NT servers are configured with a class C netmask.
So just to prove my point I started playing with the IP addresses of my QNX
What I found surprised me. It seemed that once QNX’s TCPIP knew or an
IPaddress/MACaddress combination, if I changed the IP address it would no
longer communicate. This was not the way it was in QNX4 / TCPIP V4.
Has this changed? Is it on purpose?
