Only from ICMP echo-request based DDoS', others will still be available. 
They'd have to block all traffic to their broadcast addresses, which is
pretty much what ``no directed broadcast'' does anyway.


In any case, I find scanning for SMURF amps and scanning for
vulnerabilities to be quite different.

Can't say I agree, since in fact they are both "vulnerabilities".


This is already too damn close to the usual thread about the other
active scan for my comfort.
