Re: scripts to map IP to AS?

I should have been a bit more specific.  The hacked up traceroute-ng
queries the radb, not a whoisd.  I've never had problems
being blocked when doing radb queries, but YMMV, of course.  I also
suggest that people be nice and rate-limit their queries so that
others don't have to do it for them...

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:

  http://nms.lcs.mit.edu/software/ron/lookup_as.c

Compile with

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

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