Be aware that there may be a bootstrapping problem with this.
The ICMP netmask request is broadcast, not sent only to the server,
and SUNs (3.3 at least) take the first reply received.
So if there are subnet-capable machines that haven't got the word yet,
they might propagate wrong broadcast masks. If you wire the netmask
into the server, and then either take other hosts down or feed them
the right mask, just once, everything should work after that :->.
