I can only assume my NIC (or Windows) is trying to be smarter than I am, since I always have *unremovable* routes of 192.0.0.0 and 224.0.0.0 added. Haven't played enough to know if this is normal behavior or not:
C:\\WINDOWS>route print
Active Routes:
Network Address Netmask Gateway Address Interface Metric
0.0.0.0 0.0.0.0 192.168.0.110 192.168.0.35 1
127.0.0.0 255.0.0.0 127.0.0.1 127.0.0.1 1
192.0.0.0 255.0.0.0 192.168.0.35 192.168.0.35 1
192.168.0.35 255.255.255.255 127.0.0.1 127.0.0.1 1
192.168.0.255 255.255.255.255 192.168.0.35 192.168.0.35 1
224.0.0.0 224.0.0.0 192.168.0.35 192.168.0.35 1
255.255.255.255 255.255.255.255 192.168.0.35 192.168.0.35 1
The .35 is me. But the issue is, I need 192.0.0.0 to go out the router, and only mask 192.168.0.255 for inbound (i.e. - we're only using those 254 addresses on the LAN). I must be missing something...
