Getting local IP address in javascript?

[Bram]

Is there a way to get the visitors *local* IP-address in javascript? I mean his LAN address like 192.168.1.x, not his regular IP-address.

I found several approaches that attempt to do this, but they either give me the external (regular) IP address, or they give 127.0.0.1 which doesn't really tell me anything. I need the local network address.

Just an alert saying "your machine's local network IP is 10.0.0.139" would be great.

Unfortunately, there is no reliable way of doing this across browsers. To know information like this could present a security threat. Still, if you are developing only for IE and you can modify the settings on the machines that this page needs to be viewed (or if the page can be run as an HTA), you could probably access this data via an ActiveXObject. At the moment, I am working on a Mac so I can't give you a definitive answer, but if I do find a way to do it locally, I will let you know.

don't think so.. the local IP address is only known to the localnet<->internet router at the browser end. Neither your server nor the browser will receive that info, iirc.
