SUMMARY: IP numbers, netmasks and network numbers

Thanks to everyone who responded. The key suggestion was along the line

"When sun networking tries to assign a netmask via /etc/netmasks, it will
look for the LONGEST POSSIBLE match and then assign the corresponding mask."

And thanks to the suggestion from Darren Dunham <> I was
even able to test it online.
ifconfig ce0 unplumb
ifconfig ce0 plumb
ifconfig ce0 inet `cat /etc/hostname.ce0` netmask + broadcast +
Then did a "ifconfig ce0" and verified that the netmask and broadcast
address were correct.
