Hi, To fix a lot of the DDOS attacks going on, we need to make sure BCP38 compliance goes up. Only way to do this I can think of, is large scale BCP38 testing. One way of doing this, is to have large projects such as OpenWRT, RIPE Atlas project, perhaps even CPE vendors, implement something that would spoof 1 packet per day or something to a known destination, and in this packet the "real" source address of the packet is included. I have been getting pushback from people that this might be "illegal". Could anyone please tell me what's illegal about trying to send a packet with a random source address? If we can get consensus in the operational world that this is actually ok, would that help organisations to implement this kind of testing. I could see vendors implement a test like "help verify network stability and compliance, these tests are anonymous" checkbox during the initial install, or something like this. Why isn't this being done? Why are we complaining about 300 gigabit/s DDOS attacks, asking people to fix their open resolvers, NTP servers etc, when the actual culprit is that some networks in the world don't implement BCP38? -- Mikael Abrahamsson email: swmike@swm.pp.se
