That's what we thought initially. Somebody processing logfiles. Doesn't look like it though. A remote machine makes our top ten list and then stays there for days. If we block on a router level then it seems to get fixed eventually on the other end.
If you're looking at the stats enough to pin down heavy usage to individual systems, it shouldn't be too much more work to track down why they're suddenly making the top ten list. i.e. is it a bug in their resolver, or were they hacked and running some scanner kit that makes heavy use of DNS, with A hard-coded into the scanner? ---------------------------------------------------------------------- Jon Lewis *jlewis () lewis org*| I route System Administrator | therefore you are Atlantic Net | _________http://www.lewis.org/~jlewis/pgp for PGP public key__________
