I really need to remember to ask for information from http://supportdetails.com/ instead of one of the numerous IP status sites. It just adds a few more useful details to the client’s IP and you can instantly mail the data or create a PDF report (no need to copy a screenshot into a Word file :-)).
And it also demonstrates a little bit the amount of data you expose to a generic server.
If you enjoy using Supportdetails then maybe our little tool is even more useful to you: http://www.browsercheck.me/
I’d be glad if you’d check it out!
