Re: SMURF amplifier block list

Just because the host addresses are theoretically valid doesn't mean
that using them is a good idea.  Those two addresses constitute less
than 1% of a network's addresses, and are very simple to configure out
of your DHCP servers, etc.

Again, the likelihood that these addresses will cause problems or
experience connectivity issues is a far greater concern than the gain of
less than 1% of usable address space.

Sorry Charley  :)
