Anyone want to admit privately (I'll summarize to the list) if they actively filter certain partitions of APNIC space? We did a little experiment the past couple of days and saw at 85% of our port 13[5-9] scans, Code Red/Nimda/formmail attempts, etc. go out the door by blackholing those networks in .cn and .kr. Thoughts? Is it a valid thesis? I've seen the discussions for spam mitigation, etc via DNS, but this is actually null routing all their traffic.
