After discussion some with people, I'm posting about 1 bug, 1 question
and 1 feature request. It all has to do with the 0/8 network (0.0.0.0
more specifically).

First the bug :

[trying to add a blackhole route for 0/8]
$ sudo route add 0/8 -blackhole 127.0.0.1
route: writing to routing socket: File exists

[in a second terminal running route monitor]
$ route monitor
got message of size 124 on Sat Dec 22 00:20:13 2007
RTM_ADD: Add route: len 124, table: 0, pid 15149, seq 1, errno 17, flags:
locks: inits:
sockaddrs:
default 127.0.0.1 default

[trying another way to do the same]
$ sudo route add 0.0.0.0 -netmask 255.0.0.0 -blackhole 127.0.0.1
add net 0.0.0.0: gateway 127.0.0.1
