Before I go off and find them all.... does anyone know some or all the Ips/masks I would need to block to disallow access to the whole of argentina? I don't care if it takes some more of south america with it...

Help yourself .... it's a XLS compressed into a ZIP

Regards.

In uncompressed text format.

Where do you find lists like these?

I cant remember but probably in icann or something like that

Try to look "IP assignments to ISPs" or something like that.

I guess the list changes so often. There might be a website that publicizes all of this data. Try looking for "IP Whois" ...

I am trying to find it ... if I do I will post.
