Below code will display country flag of an ip.
It can be modified to display country name too.
Code is build on c# class found at http://www.maxmind.com/app/csharp and uses data from http://www.maxmind.com/app/geolitecountry
You need to download http://geolite.maxmind.com/download/geoip/database/GeoLiteCountry/GeoIP.dat.gz and extract it to same folder with your aspx page (try winrar to extract .gz files)
You also need to download flag icons from http://www.famfamfam.com/lab/icons/flags/ and extract in to flags folder
Upload it to your server and call it like
<img src="iptoflag.aspx?ip=IPHERE" alt="" />
