Since we've begun using a nine-bit mask here (on a class B), Robert's
message concerned me.  So, I tried moving one of our Suns to a stub LAN
of our subnetted network.  In order to get the default route inserted
automatically upon booting, I had to create a file named
/etc/defaultrouter containing the ip address of a default gateway (if
this file exists, rc.local adds a static default; otherwise it starts
routed).  Since I wasn't running NIS, I also had to add the mask to
/etc/netmask.  Upon rebooting it came up just fine with it's local
network and the default gateway in its routing table.  The Sun was
running SunOS 4.1.2.
