This sample code demonstrate you on how to block the countries from accessing your website based on visitor's IP address using a non-intrusive method on application level (webpage). I'm using the BIN data file approach that will free my hassle to set up a relation database for this.
The IP geolocation BIN data provided in this sample zip is outdated, and you can always download a free IP geolocation BIN data at http://lite.ip2location.com

Virus note: All files are scanned once-a-day by SourceCodester.com for viruses, but new viruses come out every day, so no prevention program can catch 100% of them.
FOR YOUR OWN SAFETY, PLEASE:
1. Re-scan downloaded files using your personal virus checker before using it.
2. NEVER, EVER run compiled files (.exe's, .ocx's, .dll's etc.)--only run source code.
