What's the best way to find the networks in a country? I was thinking of writing some perl with Net::Whois::ARIN or some such module and loop through the block. But I think I'll have to be smarter than just a simple loop not to get blocked and I figure I'm not the first to want to do this.
If you are looking for registration data, try looking in one or more of
ftp://ftp.apnic.net/public/apnic/stats/apnic/ ftp://ftp.ripe.net/ripe/dbase/ ftp://ftp.lacnic.net/pub/stats/lacnic/ ftp://ftp.afrinic.net/stats/afrinic/ ftp://ftp.arin.net/pub/stats/arin/
(poke around and see what you can find; I didn't spend much time trying, but several/all of the RIRs seem to mirror data from all the others)
Thanks
Note that "networks in a country" is a funny phrase. The sets
- address space assigned to all organisations located in country X - routes visible in country X (from some viewpoint) - all addresses assigned to devices physically located within country X - routes that are considered "in-country" in places where billing is aligned with the necessity to traverse a long bit of wet glass
are frequently incongruent. If this matters, you might want to consider a more detailed specification of "networks in a country".
I had somewhat considered the second and the fourth point. I assumed by using whois data, I am getting the second of those options and that was good enough. If there's a way to (somewhat easily) implement the third option, I'm all ears.
