判斷IP是哪個國家的位址

http://www.maxmind.com/app/geoip_country
http://ip-to-country.webhosting.info/downloads/ip-to-country.csv.zip

這兩個網站可以下載到ip對應的國家..
但是
資料要自己從CSV匯入到SQL內

ip="168.95.1.1"
arr=split(ip)
sum = arr(0) * 16777216 + arr(1) * 65536 + arr(2) * 256 + arr(3)
SELECT country, name FROM ip_country WHERE sum BETWEEN begin_num AND end_num
