The right solution is to capture the request to these DNS servers, and
send to a custom server with a static message  "warning.html". Nothing
fancy.   With a phone number to "get out of jail", so people can call
to "op-out" of this thing, so can browse the internet to search for a
solution.


in this case, the fbi/dns-changer case, the information is pretty
straightforward for theisp folk... 'client machine makes dns queries
not to the isp dns server (or one of several free dns services), but
to a known bad set of netblocks'

the easy fix is to just stand up (forever, ha!) dns servers on the ip
blocks inside the ISP's network, done and done... they can then start
notifying the customers via mail/email/carrier-pidgeon that they are
infected, along with instructions about how to get un-infected.
