Would the above allow 192.168.1.191 and 192.168.1.192 to be valid host IPs
?. Then would require the following two routes.

route add -net 192.168.1.0 netmask 255.255.255.192
route add -net 192.168.1.64 netmask 255.255.255.192
route add -net 192.168.1.128 netmask 255.255.255.128

correct me if I am wrong.
