### thoughts about "Re: scripts to map IP to AS? ":

Are there any recommendations for caching of the results? Do, don't, not for
over 72 hours, etc? I think most people that do an AS-enabled traceroute
are always going to be getting the same answers back for the first few hops
to *ANYWHERE* - caching at least "your local neighborhood" could dramatically
cut the number of queries....

Another option would be to download IRRd and run it locally in
mirror/caching mode then just point your whois queries to it.
