Good news.

One more question (just is there is someone from the CISCO) - what's 
about source-address filtering at default for the access servers/routers? 
Note all this problems (SMURF, DENIAL-ATTACK, DNS-FRAUDING, etc etc) can 
be 100% blocked if ISP would not allow it's customers to send IP packets 
with the wrong SRC address. If not, they (hackers) should found new, new 
and new tricks to fraud any IP network.
