Re: identify hostname

I've got to go with Pete K. on this one.  In our current, cidr-ized world, it
is simply not possible for an upstream provider to determine what is, or is
not, a broadcast address in a downstream network.  This is something that needs
to be implemented from the edge in, not from the core out.
