The netmask looks ok. The machine is on a /23
img4% ifconfig -a
fxp0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 204.71.200.244 netmask 0xfffffe00 broadcast 204.71.201.255
ether 00:a0:c9:fb:47:d5

lo0: flags=8008<LOOPBACK,MULTICAST> mtu 16384
Nobody chagned start_if.fxp0 for a while also:
img4% ls -l start_if.fxp0
-rw-r--r-- 1 root wheel 130 Mar 1 08:38 start_if.fxp0
However, looking at the above I notice there is no IP given to lo0.
I'll go ifconfig lo0 -- I wonder if somehow that is the problem?
