Gadi,

This report isn't terribly useful without the IP addresses (or URLs) in
question. How could an ISP start investigating and/or null routing these
addresses without having the list?

I suppose I'm skeptical because some of those ASNs are not big content
hosters. Some are transit-only ASN's.

Also, if you are using WHOIS to check the IP addresses for their owner, how
are you correlating to ASN? Through an IRR? Or is there a route lookup
somewhere in the mix?

Even if you won't release full data (although I can't imagine why not), you
need to fully disclose the methodology. "Digested" is insufficient when ISPs
and hosters are being called out by name.

I would prefer you being skeptical. Please don't take my word on any of

How do you come up with these? Are these the direct upstream ISPs of the

Plainly put, these are the results you get when you feed the IP's of the
hosting web sites to the Cymru whois.

Is there a link to the original data?

Nope. We hope to release more data in our next reports. Please let us
know what kind of data you'd like available. We'll do our best to
provide it.

One of our main goals is public awareness, so we are very interested in
feedback.
If you have further questions on the process itself, I'd gladly direct
you to the guy who actually does the data mining and statistics - but
the list data itself is not open to the public.

Gadi.
