btw, all these keep freertr.org up on the internet so you can give it a try:
feel free to
spin up 24 windows with "telnet www.nop.hu 80" then close them and www.nop.hu
will refuse
your connections... moreover dl.nop.hu will also refuse, regardless if you
even not touched
that guy beforehand... after some minutes, both guys will accept your tcp
connections...
for this experiment, if you _beforehand_ open a session to demo.nop.hu then
you'll be able
to check when your subnet gets blackholed nop.hu wide with the command show
ipv4/6 route rtbh
