Re: scripts to map IP to AS?

  • From: David G. Andersen

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...
