Re: scripts to map IP to AS?

Careful. Many whoisds don't appreciate automated queries & will block YOUR
ip address for sometime if you cross their max query rate threshold.

  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. :)
