If you were to have a botnet which were to flood random DNS queries
for domains that did not exist to the list of DNS servers hosted on
http://public-dns.tk/nameservers-all.txt then the root dns servers and
the tld dns servers would be overwhelmed without any way to filter the
packets, if they were to filter the packets of the DNS servers, they
themselves would be turning off DNS, hence they can not do that… If
the botnet only hits the DNS…
