Let's say you buy a firewall, plug it in, and decide you want to block "all traffic that doesn't originate from the USA" (or whatever country - I'm just picking one so that I can be specific in my request).
You go through your logs and you see a hit from 126.96.36.199. You want to know, "Are there any IPs that are in the 188.8.131.52/8 range that are in the US?" Because if there aren't, you want to add that range as a block in your firewall.
Are there any sites/ways to ask such a question? I know that I can basically hack around it to see around 95% or so (looking at 5-10 IPs in that range). I'm just wondering if there's an easier way to ask that question.
