These databases don't seem to be too accurate or in agreement. I've tried to use them To block Russia, china, and a few others which has been a great help in server load but when I do a random check on someone scanning me I still get addresses in Russia and china. There's also the issue of countries leasing or selling blocks of addresses so I'll look at an address that's supposed to be in Africa but the traceroute says Singapore, for example. It's just a mess.
