You've found the blog of Leighly G Penrod (better known as Lee Penrod). Over the years I've helped thousands of people with technology questions. I started this blog to share some of the problems I've personally solved, and to act as a place to put bits of new articles before they are ready for release.
In the past I wrote serveral things published by Directron.com. I worked for them for several years including doing various bits of technical writing. Although I no longer work for them, I do still put up some content on my blog now and then.
If you are not familiar with my prior work, feel free to see these popular guides I have written-

A few quick links related to IP checking
1) PHP Subnet Calculator @ Sourceforge. A simple open source subnet calculator written in PHP. The author has a example site that is great if you need to do a simple calc from slash notation.
2) Lexdos. A simple site that shows an arbitrary IP address vs a Google Map.
3) Pear Package: Net_GeoIP. This handy little package will give you the ability to turn an IP address into a city / country / region and give you a rough guess on LAT/LONG. It does depend on a source data file put out by MaxMind but the basic version ( GeoCity Lite ) is free. The pear package + GeoCity Lite is enough to at least tell if an incoming request is from a different country -- potentially very useful for fraud detection.
