Hi Everyone,

I would like to know how spoofable Switzerland's ISP/Netowrks are. It would be very nice if some of you Swinogers would participate in my survey.
VERY spoofable.
Which is why nobody really dares to talk about it likely as it is a huge infrastructure problem that ISPs do not want to invest in to resolve.
Noting that some hardware does not allow an ISP to do proper BCP38 either (even though people have been whining at Cisco and the likes for about a decade), but it is ridiculous that the edge does not filter simply on source prefixes.
The bigger problem than hardware is simply that many ISPs do not understand why BCP38/SAVE is important to implement.
Thank your for your feedback. As expected I didn't get much responses to my survey. I have to assume many would hit the " No, and I don't care"-radio button answer... :/
But: it's not too late to answer the survey: http://goo.gl/forms/Od94HExA1d
but you are in luck, CAIDA recently took over the Spoofer project with a grant from the US government. And they are nicely going to publish and name and shame spoofable networks, please see:

and the main website http://spoofer.caida.org/
I suggest you contact KC Claffy for details about Switzerland ;)
I was already in touch with KC Claffy and Robert Beverly - nice guys! I linked their project at the end of my survey - I hoped somebody will run their tool to submit some statistics.
Have a nice week!
