[nsp-sec] 700K Open Resolver List

[Stephen Gill]

Hi Team,

I took a somewhat restrictive view of the pcaps we have and parsed out about
700K open resolvers used in the latest DNS amplifier attack across ~10K
ASNs.  I believe there were closer to 1 Million total.

You can find the data split up by ASN here:

ASNs affected:

Please do not download the entire list and only fetch the ones you have
control or influence over.

Comments/questions welcome & have a great weekend!

Cheers,
-- steve
