A list of 27 million open resolvers would be a pretty convenient input for
miscreants who want to abuse them, I believe? I assume Jared & co doesn't
want their collected work to be abused like that.
I quickly scripted a RIPE-based ASN lookup tool for myself just so I could
look up my own and customers AS-based IP ranges atleast. Thank you so much
for making the site available, Jared. Very helpful!
