Did you try on the bind list?

Yeah, ok... You got burned by ADMROCKS. Well known bind hole.
Very well known bind whole. The script kiddies are scanning for bind
servers using massively parallel scanners.

Ok... I'm not quite sure what you are after (I know what you
are literally asking and it's probably why no one has answered you).
Is this from the failure when they broke in or are you having problems
NOW after the upgrade. What was this trace from?

I don't know. It could be the trace from the IXFR buffer overflow
that ADMROCKS takes advange of. Was this from the logs during the breakin?

If you are trying to get help getting your bind server up or
analyzing an ongoing breakin attempt, say so. Just asking us to translate
a trace into a form you can understand is not going to get you very far.
Asking for us to translate a trace with no information about when and
where it came from and what was happening at the time is going to get
you even less.

Bind WHAT? I know of bind 4.x (old) and bind 8.x (current) and
bind 9.x (up and coming) but I know of no bind 2.x.
