More on Javascript IP tracking
I talked about getting TimeZone data a few days ago to figure out where IP addresses are located. I realized something while working with them, I will never see the time zone data for a visitor without JavaScript. This statement alone sounds disheartening until you realize what does not have JavaScript, and that would be SearchEngineSpiders. If you have visits from an IpAddress and it never shows you it’s resolution, colordepth or timezone then it has JavaScript turned off or it never had JavaScript to begin with. If that same IpAddress also never has an Referer data or Cookies, then the chances of this being a WebBot or SearchEngineSpider go up an order in magnitude. It’s all about realizing what the data means, not what data your can get … I’m already devloping tools to incorperate this data into the IP Address Database that I am working on at http://ipd.spiderhunter.com
