Thanks for your help. I need to determine the zip code from a given IP address. I've checked with the Maxmind GeoIP but their database doesn't have zip codes. Hmm, let me see how to get it done with the free database from http://lite.ip2location.com.
Hey thanks for the great job! Will test the module later on as I have just get the official IP2Location Nginx module at their website. Need sometime to get it done :)
