It's usually better not to run DNS resolution on the IP addresses you
have because DNS is so volatile[1].  Mapping host names to IP address
is rather expensive, too, and the casual bot-hunter may not have the
necessary tools.  (And I doubt that many bot hunters work at
web-hosting companies...)

Timestamps are usually required to pin-point an attack, but if the
compromised hosts are mostly largish web servers, they should have
static IP addresses and some kind of accounting where you can see that
something went terribly wrong.

[1] I assume you have verified those host names using a forward
    lookup.  Relying on PTR records alone is not a good idea.
