ARIN keeps a list of first-level allocations. A whois query to whois.arin.net for the IP address of interest should provide you with a record, from which you can retrieve the country code and see if it evaluates to AU. Try it - run 'whois 203.1.2.3 | grep "^country:"' in a terminal. Lovely. Repeat with any IP address you like, maybe even write a bit of awk or sed or something to strip out everything except the country code. Problem is, that ARIN (like most whois operators) doesn't want everyone hammering their whois servers, so if you make more than a certain number of queries in a certain time period, the server will just stop answering you for a while (a day or two, normally). Not what you're after, I'm sure. So some companies have stepped up to the plate to fill the void. There are several databases which have collated all of the ARIN info (or by some other means) and put it into a database for your use. You can get a lot of them by googling for "IP Address country database" (at least, it worked well for me about 20 seconds ago). Most of them appear to cost some money. Hope this speeds you on your quest. - Matt -- SLUG - Sydney Linux User's Group - http://slug.org.au/ More Info: http://lists.slug.org.au/listinfo/slug
