I am working on an application wherein I want to track clients public IP address. I don't want to use  as its an insecure connection.  Is it possible to get clients public IP address using core javascript?  Thanks

I need to somehow retrieve the client's IP address using JavaScript; no server side code, not even SSI.  However, I'm not against using a free 3rd party script/service.

Possible Duplicate:          I have a bunch of windows computers and due to a monitoring need I need to check their (static) ip address history.   When the user changes the ip address is there anywhere the ip address gets saved, logged or cached in any form at all? (I don't even need times, the simple ip address would do)

How do I get a remote host IP address if I don't have ping, and don't have any bind utilities like dig, nslookup, etc?  I need an answer that does not include 'install X' or 'use sidecar container'. I am looking for something that relies on nothing more than bash and the basic shell commands.

How can I get a list of the IP addresses or host names from a local network easily in Python?  It would be best if it was multi-platform, but it needs to work on Mac OS X first, then others follow.  Edit: By local I mean all active addresses within a local network, such as 192.168.xxx.xxx.  So, if the IP address of my computer (within the local network) is 192.168.1.1, and I have three other connected computers, I would want it to return the IP addresses 192.168.1.2, 192.168.1.3, 192.168.1.4, and possibly their hostnames.

I'm wondering if it's possible to sandbox JavaScript running in the browser to prevent access to features that are normally available to JavaScript code running in an HTML page. For example, let's say I want to provide a JavaScript API for end users to let them define event handlers to be run when &quot;interesting events&quot; happen, but I don't want those users to access the properties and functions of the window object. Am I able to do this? In the simplest case, let's say I want to prevent users calling alert. A couple of approaches I can think of are:  Redefine window.alert globally. I don't think this would be a valid approach because other code running in the page (i.e., stuff not authored by users in their event handlers) might want to use alert. Send the event handler code to the server to process. I'm not sure that sending the code to the server to process is the right approach, because the event handlers need to run in the context of the page.  Perhaps a solution where the server processes the user defined function and then generates a callback to be executed on the client would work? Even if that approach works, are there better ways to solve this problem?

I understand the reason public IP addresses are necessary to be that if we only had MAC to move data between one host and another, the entire Internet would be one massively flat network. But what is the need for private IP addresses? Why can't routers just connect to local clients using their MAC address?

When I type mynewdomain.com into my browser I believe the following happens.   My computer sends a request to my ISP's name servers to find the IP address of mynewdomain.com My ISP name server sends a request to the "." name server. The "." sends a response back to the ISP name server, saying try using the com. nameserver. My ISP name server sends a request to the com. nameserver. The com. nameserver finds mynewdomain.com. and sends my ISP nameserver back the A record. My ISP nameserver sends this back to my computer.    My question is about step 5. How does mynewdomain.com. get into the list on the com. nameserver? And given that there are hundreds of millions of registered .coms, how does it find mine in such a short time?

I know there is a single line of a command and its arguments that can help display all computer IP addresses (those that are being used) on a LAN, and my computer is also a client, as one of those displayed, but I forgot. What is it?
