I have been running the anvil for a couple of days now.  Using this
script I am able to see that most of it is stuff that is in the subscriber
networks.  However, it does help when they keep pounding.

I could not get the 'dig' line to work as posted Len so I changed it
just a little.

PTR=`dig -x $IP | grep -v ";" | grep PTR | awk '{ print $5}'`

Appreciate your pointers on anvil.  Looks like another useful tool.
