Determine device public ip
android, networking
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.
Problem
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
