            For starters, don't use IE. Opera and Mozilla are both excellent
alternatives that include many useful features without all the security risks
(have you noticed how many security updates Microsoft has released for
Internet Explorer over the years?).

            I'll assume you're writing Java code (otherwise why else would you post
your question here?), and that your .CHM has a Java Applet embedded or is
causing a Java Application or Java Servlet to start which returns the IP as a
result.

            The easy way to read a web page is to use the Java HTTP Component, for
which some simple documentation can be found here:

            For more information about HTTP (which I assume you don't need, but
perhaps other readers may find it helpful), visit this web page:
