How can it give you your private IP address? I'm curious...

Is there a javascript call to list the IP addresses of any machine? That feels very insecure to me.

EDIT: Sorry I forgot to turn on my joke detector.

It probably gets it from the X-Forwarded-For HTTP reader inserted by his intranet proxy.

Uh, no? Knowing your public IP is valuable information sometimes and you need an external source to tell you that. Knowing your machine's IP is not something you should go to a website to look up, just check your local config.

Thanks for the feedback, it should now display the correct HTTP_X_FORWARDED_FOR-header if available.

Pics or it didn't happen.
