Greetings,
        I am looking for a list of IP addresses/ranges broken down by
country of ownership.  Does anyone know of such a list?  I'm looking to
apply this list to my firewalls and range checking is easier and faster than
simply applying one ofs.  I'll take my chances on blocking legitimate
traffic.

        We've gotten rather tired of failed break in attempts from off shore
hackers and spammers.  Last night I blocked an IP range because of an attack
based in China, (anyone ever hear of HLTT Communications?) and it was put to
me to basically block access to any IP not based in the northwestern
hemisphere.  China is just the final straw, there are many others.

Thanks,
