i think the recent dns cache-poisoning vulnerability
is more self promotion than substance. my friends
at [dns operator] agree.
however, ndb/dns does use randomized query ids.
you can use snoopy to verify this or you can read
the source. (ndb/dnresolv.c/^queryns) so it is not
vulnerable.
the other part of this promotion was selling dnssec.
i'm not sold. see the five objections to dnssec in
the second paragraph.

next up, the exploit remix.
