Our private network currently uses 192.168.0.0/24 (subnet mask 255.255.255.0). We're out of IP addresses. I would simply like to supernet and change our network to 192.168.0.0/16 (subnet mask 255.255.0.0). I know I'll be treating a class C range as a class B, but will it work? Research I have done so far says it will and it will save a lot of time. We have a Cisco PIX firewall.
