I would like to restrict access from certain countries to content on my network (for security and legal reasons).So far the best algorithm I've been able to come up with is a combinationof reverse DNS and APNIC/ARIN/RIPE whois queries. I've written a perl cgi that checks reverse DNS first, and if there is no gtld country code for the reverse mapping, does a whois query and parses the response for the address.
If you're in the market for a commercial solution, Ixia do one: http://www.ixiacom.com/products/paa/netops/IxMapping.phpI don't know where they get their data from, how accurate it is, or what it costs, but I thought I'd mention that there is at least a way to make the problem someone else's by the simple application of money :)
