I'm sorry for the intrusion, I'm not a "North American Network Operator", but what I'm going to say could (I hope) be relevant to all the Internet community.
.... 194.184.1.0 194.184.148.0 194.184.179.0 194.184.204.0 .... 195.223.41.0
You'll probably have few luck trying to make even one of routers on these netowks fixed. It's because these netblocks are allocated to Interbusiness, an italian NSP who mainly sells connectivity to other ISPs and companies. They refuse to give access to the routers installed on the customer's side, so, EVERY network (mostly /24s) in their allocations could be a smurf amplifier if enought hosts are connected. Their allocations are: 194.184/16 195.223/16 195.31/16 195.103/16 195.120/16 212.210/16 One could argue that having access to all the routers on the customer's side could enable them to put a "no ip directed-broadcast" on all their routers (all ciscos) in a minute, but unfortunatelly interbusiness is well know to have all role accounts @interbusiness.it redirected to /dev/null. I'll try to do my best to contact them and make their routers fixed.
