Hey guys, I thought I'd share my site with you: http://www.ipconfig.ie
It's just a simple site to show end users their Public IP Address and what ISP they are currently using! Let me know if you find it helpful :)
It reads the ISP name from ARIN (USA) and RIPE (Europe) but also gives users the option to type in an ISP description and vote, if the one that appears is inaccurate.
