gw1500se,

Some routers use JavaScript to dynamically create an html page using document.write. As you have already been told LWP and WWW::Mechanize do not support JavaScript, see how to reboot adsl modem with perl? for a similar problem, and list of WWW::Mechanize variants that do support JavaScript.

I don't know what you mean by 'fooling Server' but depending on the JavaScript in question it is often possible to write some Perl that provides the same function as the JavaScript does. If all you are looking for is the IP address assigned by your ISP, perhaps you could simply use WWW::Mechanize to get http://www.whatismyip.com (or similar service), and parse the response.

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
• Want more info? How to link or How to display code and escape characters are good places to start.
