Anybody have a pointer to scripts to map IP to AS? 

There are still 10K-20K hosts spewing M$SQL slammer/sapphire packets, 
and I'd like to start blocking routing to those irresponsible AS's 
that haven't blocked their miscreant customers.


  You can use a quick perl wrapper around whois, or you
could use this terribly ugly hacked up traceroute-ng that I
wrote to do lookups:


Compile with

   gcc -DSTANDALONE=1 lookup_as.c -o lookup_as -lm

And then run.  It gets the job done, but it's ugly. :)
