I originally wasn't going to make the whole thing avaiable, but there was a posting a few ago on nanog listing a number of blocks, so I feel obliged to post a link to my results. I plan on putting a nice backend behind this and making it a queryable database that checks itself frequently, but I've not had the time.
This list is the result of about a weeks worth of work probing a total of 48394 netblocks. Of those netblocks, 6425 were found to respond with more than one packet sent to the network address. broadcast address of 255 was not checked, nor anything else than the list here. This means 13.28% of netblocks out there are "broken".
If you added a scan to check the class B nets as /24 nets I am pretty sure you would get a huge increase in broken nets. ----- Mikael Abrahamsson email: swmike@swm.pp.se
