ip address of client system

Question

how to get ip address of client system through JavaScript

Answer 1

You can't, at least not directly (I've seen tricks which work via interfacting with Java), or reliably.

Which IP address anyway? I've used workstations which have had as many as 6!

Answer 2

I don't think you can without some server interaction.

The easiest way would be making an AJAX request to a server-side snippet that, in PHP, would look like this:

<?php echo $_SERVER["REMOTE_ADDR"]; ?>

Answer 3

You can't directly. One approach could be to send an AJAX request to your server (if there is one), which can return the IP address from which the user is viewing the current page.

Answer 4

you probably need an external party that will tell you; even if it were possible to get the local ip from javascript (which I doubt) you will most of the time get private ip address in ranges 10.x.x.x or 192.168.x.x (or that other one which I just can't seem to remember)

So put the ip in the page by php, like suggested above, of have a dedicated script echoing just the remote ip. That will then be the ip you have as seen from on the internet.
