Re: scripts to map IP to AS?

Hi Johannes,
] > Anybody have a pointer to scripts to map IP to AS?
] Grab a routing table snapshot from the routeviews archive and run it
] through parse_bgp_dump from CAIDA's CoralReef package. Then use
] CAIDA::ASFinder or Net::Patricia to do the lookups.
In fact I have 2 scripts to do just this.
- Script #1 uses a route-server for a smallish list of IPs.
- Script #2 uses the method listed above and pipes IPs into the CAIDA
lookup tree of a BGP table offline. Once you've installed CoralReef
it's really not much more work to get the customization you need for
lookups.
Contact me off-list if you're interested in either one.
Cheers,
-- steve
