This is encouraging news:
I ran a scan for smurf-amps of /24s in 200/8 through 210/8 in late July that yielded 30,083 networks that returned duplicate echo-replies. Today, I rescanned those networks, and found that of the original 30k, only 21,255 returned duplicates -- that's a 29% drop.
Whether it means that more networks overall are properly configured, or that different networks are misconfigured, I know not. Optimistically, I'd like to guess that the former is true, but a complete scan would be necessary to know.
Its an actual across-the-board drop. If you eliminate the puny bcasts (less then 10 dupes) the numbers are even better. I've got a project setup to automatically scan everything in the bgp routing table, grab contact information for the UPLINK (99.9% of those bcasts remaining are ones with dud contact info), send out aggregated emails to said uplinks, and maintain a database of useful statistics. The only thing I'm waiting on is certain persons coughREIDcough coughSTEVEcough to get off their arses and finish what they said they would a couple months ago. =) -- Richard Steenbergen <humble@lightning.net> http://www.bitchx.com/~humble humble@EFnet hkp://keys.pgp.com/humble@lightning.net PGP KeyID: 0x21581362 PGP key fingerprint: 7552 6AB2 B9C7 5A1B F1B6 8EA3 DFCF 793D 2158 1362 "I tried sniffing Coke once, but the ice cubes got stuck in my nose!"
