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:
gcc -DSTANDALONE=1 lookup_as.c -o lookup_as -lm
And then run. It gets the job done, but it's ugly. :)
