Determine device public ip

Issue

Does anyone know how I could get the public ip address of an android device?

I am trying to run a server socket (just experimenting with simple p2p).

This requires informing the local and remote users of each others public ip. I did find this thread How to get IP address of the device from code? which contains a link to an article (http://www.droidnova.com/get-the-ip-address-of-your-device,304.html) that shows how to get the IP. However this returns the local ip when connected through a router and I would like to get the actual public IP instead.

TIA

Solution

Just visit http://automation.whatismyip.com/n09230945.asp and scrape it?

whatismyip.com is perfect for getting the IP, though the site requests you only hit it about once every 5 minutes.

UPDATE FEB 2015

WhatIsMyIp now exposes a developer API that you can use.
