Traditionally 192.*.*.* are "Class C" networks: ones that have a
netmask of 255.255.255.0 . So everybody will use THAT netmask and
corresponding broadcast address when none is given. Newer kernels
are reportedly adding routes by itself, for which I don't understand
the reason, and got bitten by yesterday.
