[Sanctuary]

This PHP script will tell who ever is viewing it their current IP address.

Demonstration: http://sancstestsite.comli.com/checkmyip/

It is no-where near malicious and does not log your IP. That's a whole different script.

Here's the download link: http://www.mediafire.com/?aac5vifh4rck4sx

To edit whatever part of the script you want, just open it up in Notepad or Notepad++ and edit the parts you want to edit.
After that, just save it and upload it back onto your website.
