Jeeze, peeps, get a grip. That information, regardless where it is displayed or not displayed, is provided by your browser to ANY website that you visit. This is how the internet works with browsers. It's standard operating protocol. That Dynasoft script runs serverside, thus it simply acts like a mirror, reflecting back to you your own information. The info it is showing you is also available to the website operator. That is how forums can ban individuals based on their IP, and it is also useful to website operators in determining your browser type so that the web page you view can be displayed properly on any given browser. I run several websites and all of the sites log that very same data so that we can determine how to better present our content to our audience and to analyze the demographic of our audience. Nothing fradulent going on here. Just a clever useage of a server side script to convert that information into a graphic and inserting it into the sign. There are numerous free PHP and CGI scripts available which will accomplish that very task provided your hosting company allows you to run CGI or PHP content and they must also have a graphics manipulation module such as ImageMagick or GD installed on the server as well.
Also of note, whenever you send an email from your home PC to anyone, they can open the header information in their mail program and instantly see what IP address the message originated from, unless it was altered or spoofed. Then, doing a "reverse DNS lookup", they can find out your provider's information and in some cases, the locale (based on router information provided in the trace route).
Abbie....
